DESCRIPTION OF EMBODIMENTS

[0088] As illustrated in FIG. 1 and the following drawings, a door handle device is configured to include a handle unit 10 which links a movable handle that functions as an operating member 3 to a fixed handle that functions as a base 2, and an output portion unit 12 which holds an output portion 4 to a unit base 11.

[0089] Fixing of the handle unit 10 to a door 1 is performed by fixing the fixed handle to a front surface of a door panel (door 1) in a posture in which a left side is oriented toward a front part of a vehicle in FIG. 1 (hereinafter, in the specification, “upward-and-downward” and “forward-and-rearward” directions are defined considering a posture of being attached to a vehicle as a standard, the upward direction in FIG. 4 is a “front surface side”, and a side opposite thereto is “rear surface side”).

[0090] In addition, as illustrated in FIGS. 1 and 4, in the door panel 1, a recess portion 1a for ensuring an insertion space of a hand is formed between the front surfaces of the door panel 1 when performing an opening operation of the door 1, and further, front and rear portion mounting openings 1b and 1c for fixing the fixed handle 2, are installed to be open.

[0091] As illustrated in FIG. 5, the fixed handle 2 includes door attaching surfaces 2a in a front and rear end portions, and at the center portion thereof, a handle corresponding portion 2b which corresponds to the recess portion 1a of the door panel 1 and floats up from the front surface of the door panel 1, is provided.

[0092] Fixing of the fixed handle 2 to the door 1 is performed by screwing a fixing block 16 formed at the rear end portion to the door panel 1 after inserting the fixing block 16 into the door 1 from the rear portion mounting opening 1c, and by mounting an appropriate clip member which is inserted into the door 1 from the front portion opening 1b on the front end portion. In the fixing block 16, a screw insertion through-hole 16a which is used in screwing to the door panel 1 is provided (refer to FIGS. 3 and 4).

[0093] In the movable handle 3, one end is pivotally supported to be freely rotatable by a hinge protruding piece 2c that enters the door 1 in a state of protruding from the front end of the fixed handle 2 and being fixed to the door 1, and is held at an initial rotation position illustrated in FIG. 4.

[0094] In addition, in the fixed handle 2, a fitting groove 2d for accommodating the movable handle 3 is formed to longitudinally pass (refer to FIG. 2), and further, in the movable handle 3 and the fixed handle 2, the movable handles 3 respectively exceed the initial rotation position, and a stopper (not illustrated) for regulating the clockwise rotation in FIG. 4 is provided.

[0095] The movable handle 3 has a length that exceeds the handle corresponding portion 2b from a linking end linked to the fixed handle 2 and reaches the rear end portion of the fixed handle 2, and in an intermediate portion, a handle portion 3a which corresponds to the handle corresponding portion 2b of the fixed handle 2 is formed. As illustrated by a chain line in FIG. 5, when the movable handle 3 is at the initial rotation position, the handle portion 3a overhangs toward the rear surface side from the handle corresponding portion 2b of the fixed handle 2, and an operation with respect to the front surface side is ensured.

[0096] In addition, as illustrated in FIGS. 3 and 5, in the rear end portion of the fixed handle 2, a pin receiving block 17 and a pin receiving piece 18 are installed to protrude toward the rear surface, and a lever 14 and a counter weight 20 are coaxially linked to each other around a rotation shaft 19 which is built between the pin receiving block 17 and the pin receiving piece 18 and is disposed in the upward-and-downward direction.

[0097] The lever 14 includes a moved piece 14a which overhangs toward the front part in one end portion, and an operating piece 14b which is provided with a fork-shaped linked portion 13 at a tip end and overhangs toward the rear surface side, is formed in a substantially L shape, and is pivotally supported in the vicinity of a curved portion.

[0098] As illustrated in FIG. 4, in a state where the output lever 14 is mounted, the tip end of the moved piece 14a corresponds to the rear end portion of the movable handle 3, and the lever 14 rotates between an initial rotation position determined by the initial rotation position of the movable handle 3 and an operation rotation position that abuts against a lever stopper portion 2e in which the moved piece 14a is formed in the fixed handle 2, as illustrated in FIG. 6.

[0099] The counter weight 20 is formed of a metal material, such as zinc die cast, such that a predetermined weight is generated, and moves the center of gravity to the rear part by disposing a weight portion 20a having a large capacity at the rear part with respect to the rotation shaft 19 (refer to FIGS. 3 and 4).

[0100] The counter weight 20 abuts against the lever 14 being biased in a counterclockwise direction in FIG. 4 by a torsion spring which is not illustrated, and rotates following the rotation of the lever 14 toward the operation rotation position (in a clockwise direction in FIG. 4).

[0101] In addition, the counter weight 20 freely revolves in the clockwise direction with respect to the lever 14, and when the lever 14 is at the initial rotation position, it is possible to rotate only the counter weight 20 in the clockwise direction.

[0102] Therefore, in the example, in a non-operating state (initial state) where the handle unit 10 is fixed to the door 1, as illustrated in FIG. 4, the lever 14 is held at the initial rotation position by a biasing force of the counter weight 20, and according to this, the movable handle 3 pushed to the moved piece 14a of the lever 14 is held at the initial position.

[0103] When hooking a fingertip to the handle portion 3a from the state and pulling the movable handle 3 to the front surface side, as illustrated in FIG. 6, the lever 14 and the counter weight 20 are pressed to the movable handle 3, rotates in the counterclockwise direction in FIG. 6, and moves to the operation rotation position.

[0104] In addition, in the initial state illustrated in FIG. 4, in a case where a side surface collision force is applied in an arrow A direction, an inertia in the operation rotating direction acts on the movable handle 3, and the lever 14 rotates in the operation rotating direction, a rotating force in the counterclockwise direction is generated by the inertia in the counter weight, an operation of the lever 14 is regulated, and releasing of a locked state of the door 1 is avoided.

[0105] Furthermore, in a case where a side surface collision force in an arrow B direction is applied in FIG. 4, since only the counter weight 20 rotates in the clockwise direction and the lever 14 does not rotate, the releasing of the locked state of the door 1 is avoided.

[0106] Meanwhile, as illustrated in FIG. 7 and the following drawings, the output portion unit 12 is formed to mount a cam body 7 and the output portion 4 configured of a linking slider on the unit base 11, and is fixed to the door 1 from the rear surface of the door panel 1. As illustrated in FIGS. 7 and 8, in the unit base 11, an attaching piece 11a for being jointly fastened to the door panel 1 together with the fixing block 16 of the fixed handle 2, and a locking claw 11b for locking to a circumferential edge of the rear portion opening 1c of the door panel 1, are formed.

[0107] As illustrated in FIGS. 9 and 10, the cam body 7 includes a rod-like linking portion 15 at one end, includes two blade pieces 7a which oppose the other end, and includes a rotation shaft insertion through-hole 7b installed to be open in the intermediate portion. In each of the blade pieces 7a, a long hole-like cam portion 6 having a width dimension by which a follower pin 9 which will be described later can be inserted to be freely movable is formed.

[0108] A linking slider 8 includes a pin stator 8a at one end and a wire linking hole 8b for linking an inner wire of a cable device 21 at the other end, is formed in a rectangular shape, and after being fitted to be nipped between the blade pieces 7a of the cam body 7, the linking slider 8 is linked by the follower pin 9 which penetrates the cam portion 6 and the pin stator 8a.

[0109] As illustrated in FIGS. 9 and 11, after being mounted on a slide guide 22, the cam body 7 which links the linking slider 8 as described above is linked to the unit base 11 by a linking pin 23 which penetrates the rotation shaft insertion through-hole 7b and a cam attaching hole 11c formed in the unit base 11 (refer to FIGS. 7 and 12). As illustrated in FIG. 8, in the slide guide 22, a cable linking recess portion 22a for linking an outer cable of the cable device 21 linked to the linking slider 8, is formed.

[0110] The slide guide 22 is formed to open a guide long hole 22c into which the above-described follower pin 9 can be inserted, in one pair of blade pieces 22b that nip the cam body 7 therebetween, and the cam body 7 is incorporated by allowing the follower pin 9 to pass through from an opening end of the guide long hole 22c.

[0111] In the above-described output portion unit 12, the cam body 7 is held at the initial rotation position illustrated in FIG. 7 by a spring which is not illustrated, the linked portion 13 of the lever 14 is fitted to the linking portion 15 of the cam body 7 in accordance with the linking operation of the handle unit 10 and the unit base 11, and then, the linking slider 8 slides in accordance with the operation of the movable handle 3 of the handle unit 10, and a door lock device 5 is operated via the cable device (refer to FIG. 2).

[0112] Next, the action of the cam body 7 will be described in detail. As described above, when performing the rotation operation with respect to the movable handle 3 from the initial rotation position to the operation rotation position in a state where the handle device is attached to the door 1, since a lever ratio between a transmission side and a transmitted side between the movable handle 3 and the lever 14 and between the lever 14 and the cam body 7 is substantially constant in the entire operation process of the movable handle 3, ratios between an operation angle with respect to the movable handle 3 and an operation angle of the cam body 7 substantially match each other in the entire operation process.

[0113] Meanwhile, as illustrated in FIG. 10, the cam portion 6 which configures a transmission portion of the cam body 7 and the linking slider 8 is formed such that a distance (d) from the rotation center of the cam body 7 gradually decreases as moving from the initial rotation position toward the operation rotation position. As a result, when the cam body 7 rotates from the initial rotation position, the linking slider 8 linked to the cam portion 6 is pulled in the rotation center direction of the cam body 7, that is, the 2A direction of FIG. 2, and operates the door lock device 5.

[0114] Furthermore, the cam portion 6 is set such that an increment (Δd) of the distance (d) from the rotation center with respect to the same increment (Δθ) of the rotation angle of the cam body 7 increases at an initial state of the rotation, and decreases at a later stage of the rotation.

[0115] FIG. 14 illustrates the increment (Δd) of the distance from the rotation center in an arrow 14A direction when the left side consecutively rotates by an increment (Δθ) from the initial rotation position and moves to the operation rotation position on the right side, that is, the sliding direction of the linking slider 8.

[0116] As illustrated in FIG. 14, the increment (Δd) at the initial state of the rotation of the cam body 7 is larger compared to that at the later stage of the rotation, and the vicinity of the minimum angle (fourth from the left in FIG. 14) substantially matches the position at which the resistance from the door lock device 5 becomes the maximum, that is, the position at which the releasing of the locked state is performed by locking the door 1.

[0117] Since the operating force generated in the cam body 7, that is, the linking slider 8 by the operation of the movable handle 3, is proportional to the moving distance of the linking slider 8 with respect to a unit rotation angle of the movable handle 3, the operating force of the linking slider 8 becomes small at the initial state of the operation of the movable handle 3 and becomes large at the later stage.

[0118] When considering a change in resistance from the door lock device 5, a relationship of the operating force (operation resistance) and an operation angle with respect to the movable handle 3 is achieved as illustrated in FIG. 13A in which a horizontal axis is the rotation angle (θ) of the movable handle 3 and a longitudinal axis is the operating force (operation resistance) (F) of the movable handle 3.

[0119] In FIG. 13A, a chain line indicates that the operation resistance becomes a peak (peak value F1) at the operation angle (θ1) that corresponds to the door lock releasing, in a graph illustrating a line that corresponds to an example of the related art in which the increment of the movement distance of the linking slider 8 with respect to the operation angle of the movable handle 3 does not change.

[0120] Meanwhile, in the embodiment in which there is a change in increment of the movement distance of the linking slider 8 with respect to the operation angle of the movable handle 3, as illustrated by a solid line in FIG. 13A, the operating force of the linking slider 8 also increases at a time (θ0) at which the resistance from the door lock device 5 becomes the maximum, and further, the operating force of the linking slider 8 also decreases at a stroke initial stage at which the resistance from the door lock device 5 is small, and thus, the peak value (F0) of the operation resistance of the handle moves forward, and the peak value also becomes small.

[0121] Therefore, in the embodiment, while it is possible to reduce the maximum operating force of the movable handle 3, the change in operating force that reaches the peak value is smooth, there is not a case where the movable handle 3 suddenly becomes heavy, and thus, operability becomes excellent.

[0122] In addition, the peak value, the timing at which the peak value is achieved, and the change to reach the peak value can be appropriately changed according to the design of the cam portion 6, and for example, as illustrated by a broken lines in FIGS. 13A and 13B, it is also possible to shift an operation angle (θ2) to the rear part during the peak, and to reduce a peak value (F2).

[0123] In addition, it is also possible to improve the operation feeling by designing a cam portion 106 such that a change rate that reaches the peak value becomes smoother.

[0124] A relationship of the operation feeling and the change that reaches the peak value is illustrated in FIG. 13B in which a horizontal axis is a rotation angle (θ) of a movable handle 103 and a longitudinal axis is a ratio of a change in operating force of the movable handle 103.

[0125] In FIG. 13A, as illustrated by a solid line, by decreasing the maximum operating force of the movable handle 103 and by making the change in operating force that reaches the peak value smooth, as illustrated by a solid line of FIG. 13B, a change rate (jerk) of the operating force per operation angle decreases without a limit in a section immediately after starting the operation and immediately before finishing the operation.

[0126] Therefore, in the embodiment, since it is possible to reduce the change rate of the operating force per operation angle of the movable handle 103, it is possible to reduce unpleasant rattling which occurs in accordance with the operation of the movable handle 103, and the operation feeling is improved.

[0127] In addition, above, a handle device in which the movable handle 3 is linked to the fixed handle 2 in advance and which is fixed to the door 1, is described, but the invention can also be employed in a handle device in which the base 2 is fixed to the rear surface of the door panel 1 in advance and the movable handle 3 that provides a handle when performing the opening operation with respect to the door 1 is mounted on the base 2 from the front surface side of the door 1 as the operating member 3.

[0128] FIGS. 15 to 28C illustrate an embodiment configured as an outside handle device.

[0129] The outside handle device is configured to include a handle unit 116 which links an operating member 104 to a fixed handle that functions as a base 115 in advance, and a linking unit 118 in which a linking portion 107 is disposed in a unit base 117.

[0130] The handle unit 116 is attached to a door 101 in a posture in which a left side is oriented toward a front part of the vehicle in FIG. 15 (hereinafter, in the specification, “upward-and-downward” and “forward-and-rearward” directions are defined considering a posture of being attached to a vehicle as a standard, the upward direction in FIG. 18 is a “front surface side”, and a side opposite thereto is “rear surface side”).

[0131] In a door panel 119, front and rear portion mounting openings 119a and 119b (refer to FIG. 15) which are installed to be open for fixing the fixed handle 115, and a recess portion 119c (refer to FIG. 18) for ensuring an insertion space of a hand between the front surfaces of the door panel 119 when performing an opening operation of the door 101, are formed.

[0132] As illustrated in FIG. 19, the fixed handle 115 includes a door attaching surface 115a in a front and rear end portions, and at the center portion thereof, a handle corresponding portion 115b which corresponds to the recess portion 119c of the door panel 119 and floats up from the front surface of the door panel 119, is provided.

[0133] Fixing of the fixed handle 115 to the door 101 is performed by screwing a fixing block 115c formed at the rear end portion to the door panel 119 after inserting the fixing block 115c into the door 101 from the rear portion mounting opening 119b, and by mounting an appropriate clip member which is inserted into the door 101 from the front portion opening 119a on the front end portion. In the fixing block 115c, a screw insertion through-hole 115d which is used in screwing to the door panel 119 is provided (refer to FIGS. 17 and 18).

[0134] Meanwhile, in the operating member 104, one end is pivotally supported by a hinge protruding piece 115e that enters the door 101 in a state of protruding from the front end of the fixed handle 115 and being fixed to the door 101, and the operating member 104 rotates between the initial position illustrated in FIG. 18 and the emergency corresponding position illustrated in FIG. 20. The rotating direction of the operating member 104 is set to match a direction in which a free end is pulled to the outside of the door 101 when moving to the emergency corresponding position, that is, the rotating direction of the door 101.

[0135] As illustrated in FIG. 17, the operating member 104 is accommodated in a fitting groove 115f formed to longitudinally pass the fixed handle 115, and in the operating member 104 and the fixed handle 115, the operating member 104 exceeds the initial position, and a stopper (not illustrated) for regulating the clockwise rotation in FIG. 18 is provided.

[0136] The operating member 104 has a length that exceeds the handle corresponding portion 115b from a linking end linked to the fixed handle 115 and reaches the rear end portion of the fixed handle 115, and in an intermediate portion, a handle portion 104a which corresponds to the handle corresponding portion 115b of the fixed handle 115 is formed. As illustrated by a chain line in FIG. 19, when the operating member 104 is at the initial position, the handle portion 104a overhangs toward the rear surface side from the handle corresponding portion 115b of the fixed handle 115, and an operation with respect to the front surface side is ensured. Furthermore, when hooking a fingertip to the fixed handle 115 and opening the door 101, an opening operating force of the door 101 is also loaded on the operating member 104.

[0137] In addition, as illustrated in FIGS. 17 and 19, in the rear end portion of the fixed handle 115, a pin receiving block 120 and a pin receiving piece 121 are installed to protrude toward the rear surface, and a lever 123 and a counter weight 124 are coaxially linked to each other around a rotation shaft 122 which is built between the pin receiving block 120 and the pin receiving piece 121 and is disposed in the upward-and-downward direction.

[0138] The lever 123 includes a moved piece 123a which overhangs toward the front part in one end portion, and an operating piece 123c which is provided with a fork-shaped output portion 123b at a tip end and overhangs toward the rear surface side, is formed in a substantially L shape, and is pivotally supported in the vicinity of a curved portion.

[0139] As illustrated in FIG. 18, in a state where the lever 123 is mounted on the fixed handle 115, the tip end of the moved piece 123a corresponds to the rear end portion of the operating member 104, and the lever 123 rotates between an initial rotation position determined by the initial position of the operating member 104 and a rotation finishing end position that abuts against a lever stopper portion 115g in which the moved piece 123a is formed in the fixed handle 115, as illustrated in FIG. 20.

[0140] The counter weight 124 is formed of a metal material, such as zinc die cast, such that a predetermined weight is generated, and moves the center of gravity to the rear part by disposing a weight portion 124a having a large capacity at the rear part with respect to the rotation shaft 122 (refer to FIGS. 17 and 18).

[0141] The counter weight 124 abuts against the lever 123 being biased in a counterclockwise direction in FIG. 18 by a torsion spring which is not illustrated, and rotates following the rotation (in a clockwise direction in FIG. 18) of the lever 123 toward the rotation finishing end position.

[0142] In addition, the counter weight 124 freely revolves in the clockwise direction with respect to the lever 123, and when the lever 123 is at the initial rotation position, it is possible to rotate only the counter weight 124 in the clockwise direction.

[0143] Therefore, in the example, in a non-operating state (initial state) where the handle unit 116 is fixed to the door 101, as illustrated in FIG. 18, the lever 123 is held at the initial rotation position by a biasing force of the counter weight 124, and according to this, the operating member 104 pushed to the moved piece 123a of the lever 123 is held at the initial position.

[0144] When hooking a fingertip to the handle portion 104a and pulling the operating member 104 to the front surface side, as illustrated in FIG. 20, the lever 123 and the counter weight 124 are pressed to the operating member 104, and moves to the rotation finishing end position.

[0145] In addition, in the initial state illustrated in FIG. 18, in a case where a side surface collision force is applied in an arrow A direction, an inertia in the operation rotating direction acts on the operating member 104, and the lever 123 rotates in the operation rotating direction, a rotating force in the counterclockwise direction is generated by the inertia in the counter weight 124, a rotation operation of the operating member 104 toward the emergency corresponding position is avoided.

[0146] Furthermore, in a case where a side surface collision force in an arrow B direction is applied in FIG. 18, only the counter weight 124 rotates in the clockwise direction and the lever 123 does not rotate.

[0147] Meanwhile, as illustrated in FIG. 21 and the following drawings, the linking unit 118 is formed to mount a linking portion 107 including a rotating body 111, a follower body 113, and a guide portion 114, and the switch member 106 configured of a micro switch, on the unit base 117, and is fixed to the door 101 from the rear surface of the door panel 119.

[0148] As illustrated in FIGS. 24 and 25, in the unit base 117, an attaching piece 117a and a locking claw 117b are formed, and as illustrated in FIGS. 18 and 20, the attaching piece 117a is jointly fastened to the door panel 119 together with the fixing block 115c of the fixed handle 115, and a locking claw 117b is locked to a circumferential edge of the rear portion opening 119b of the door panel 119, are formed.

[0149] As illustrated in FIGS. 22 and 23, the rotating body 111 includes a rod-like input portion 111a at one end, and 102 blade pieces 111b which oppose the other end, and includes a rotation shaft insertion through-hole 111c installed to be open in the intermediate portion. In each of the blade pieces 111b, a long hole-like cam portion 112 having a width dimension by which a follower pin 125 of the follower body 113 which will be described later can be inserted to be freely movable is formed.

[0150] As illustrated in FIG. 23, the follower body 113 is configured to include a linking slider 126 that includes a pin stator 126a at one end and a wire linking hole 126b for linking an inner wire of a cable device that functions as an operating force transmission member 102 at the other end, and is formed in a rectangular shape (refer to FIG. 22), and the follower pin 125, and as illustrated in FIG. 26, after being fitted such that the linking slider 126 is nipped between the blade pieces 111b of the rotating body 111, the rotating body 111 is linked by fixing the follower pin 125 to pass the cam portion 112 and the pin stator 126a.

[0151] As illustrated in FIG. 24, after being mounted on a slide guide 127, the rotating body 111 which links the follower body 113 as described above is linked to the unit base 117 by a linking pin 128 which penetrates the rotation shaft insertion through-hole 111c and a cam attaching hole 117c formed in the unit base 117 (refer to FIG. 21).

[0152] In addition, as illustrated in FIG. 25, in the slide guide 127, a cable linking recess portion 127a for linking an outer cable of the cable device 102 linked to the linking slider 126, is formed.

[0153] The slide guide 127 is formed to open the long hole-like guide portion 114 into which the above-described follower pin 125 can be inserted, in one pair of blade pieces 127b that nip the rotating body 111 therebetween, and the rotating body 111 is incorporated by allowing the follower pin 125 to pass through from an opening end of the guide portion 114, and in this state, the rotating body 111 is guided in a sliding direction of the follower body 113.

[0154] In the above-described unit of the linking portion 107, the rotating body 111 is held at the initial position illustrated in FIG. 21 by a spring which is not illustrated, the output portion 123b of the lever 123 is fitted to the input portion 111a of the rotating body 111 in accordance with the linking operation of the handle unit 116 and the unit base 117 (refer to FIG. 18). In this state, when rotating the operating member 104 from the initial position to the emergency corresponding position, the lever 123 rotates to the rotation finishing end position, and according to this, the rotating body 111 rotates from the initial rotation position illustrated in FIG. 21 to the rotation finishing end position illustrated in FIG. 27C, and as a result, the linking slider 126 slides, and the door latch device 103 is operated via the cable device 102 (refer to FIG. 16).

[0155] In addition, on the unit base 117, the switch member 106 is fixed while an actuator portion 105 is oriented toward the center of the rotating body 111. As illustrated in FIG. 24, in order to fix the switch member 106, a switch fixing plate 129 is fixed to the unit base 117, and the switch member 106 is fixed to the switch fixing plate 129 in a state of being nipped by the switch fixing plate 129 and a switch cover 130 fixed to the switch fixing plate 129.

[0156] The output of the switch member 106 is connected to a latch control circuit which is not illustrated, and when the actuator portion 105 is pushed down, as illustrated in FIG. 16, an electric actuator, such as a motor, incorporated into the door latch device 103 is driven, and the latch releasing operation is performed.

[0157] As illustrated in FIGS. 27A to 27C, a pushing portion 109 which pushes down the actuator portion 105 of the switch member 106 is formed in an outer circumferential portion of the rotating body 111. As illustrated in FIG. 27A, the pushing portion 109 finishes a pushing-down operation of the actuator portion 105 when rotating the rotating body 111 from the initial rotation position to a near operation rotation position (θA) that reaches a rotation finishing end position (θE), and after this, the pushing portion 109 is formed by a cam surface having an outline of which the pushing-down dimension is invariable by forming an arc around the rotation center of the rotating body 111.

[0158] The operation rotation position (θA) of the rotating body 111 corresponds to an operation position of the operating member 104, and as a result, as illustrated in FIG. 28A, when performing the rotation operation with respect to the operating member 104 from the initial position to the operation position (θa), the switch member 106 is pushed down and the switch is placed in a contact state.

[0159] Next, an operation of the cam portion 112 of the rotating body 111 will be described based on FIGS. 27A to 27C, 28B, and 28C. First, as described above, when performing the rotation operation with respect to the operating member 104 from the initial position to the emergency corresponding position (θe) in a state where the handle device is attached to the door 101, a ratio of the lever 123 between a transmission side and a transmitted side between the operating member 104 and the lever 123 and between the lever 123 and the rotating body 111 is substantially constant in the entire operation process of the operating member 104.

[0160] Therefore, ratios between an operation angle with respect to the operating member 104 and an operation angle of the rotating body 111 substantially match each other in the entire operation process, a relationship of the rotation of the above-described rotating body 111 and displacement of the follower body 113 substantially matches a relationship of the operation angle with respect to the operating member 104 and the displacement of the follower body 113, and the graph illustrating a relationship between the rotation angle of the operating member 104 and the displacement amount of the follower body 113 in FIG. 28B is substantially equivalent to a cam curve of the cam portion 112.

[0161] Here, with reference to FIG. 27A, a range from the initial rotation position of the cam portion 112 to the operation rotation position (θA) is formed by an arc-like long hole having a radius R around the rotation center of the rotating body 111, and in the range, the rotation of the rotating body 111, that is, the operation from the initial position of the operating member 104 to the operation position (rotation angle θa) does not cause displacement of the follower body 113 as illustrated in FIG. 28B.

[0162] In this manner, since a displacement suppression portion 110 in which the follower body 113 does not follow the rotation of the rotating body 111 in a range of the cam portion 112 from the initial rotation position to the operation rotation position (θA) is provided, the rotation operation from the initial position to the operation position of the operating member 104 only generates a disconnection operation of the switch member 106 and does not drive the follower body 113, that is, does not operate the cable device 102 at all, and thus, there is no negative influence even in a case where there is not a play in the door latch device 103.

[0163] In addition, in the displacement suppression portion 110, since the resistance from the follower body 113 does not act, the operating force of the operating member 104 is equivalent to the biasing force to the rotating body 111 or the operating member 104, and is substantially constant as illustrated in FIG. 28C.

[0164] After this, the cam portion 112 is formed to have an outline curve which approaches the rotation center of the rotating body 111 as approaching the rotation finishing end position (θE). The cam curve illustrated by a curve of the outline can be expressed by a straight line in which the displacement amount of the follower body 113 increases as the operation angle increases as illustrated in FIG. 28B, and the line of the operating force also becomes a substantially constant value as illustrated in FIG. 28C.

[0165] At this time, in FIG. 28B, in the vicinity of a boundary portion in which the displacement amount linearly increases from 100 (rotation angle θb), by generation or the like of acceleration caused by a decrease in a component of a force in the moving direction of the follower body 113 by the rotating force of the rotating body 111 due to the change in an abut state between the follower pin 125 of the follower body 113 and the wall surface of the cam portion 112, an inertia when starting the movement from a still state, or a sudden change in moving speed of the follower body 113, as illustrated in FIG. 28C, a phenomenon of a rapid increase in operating force is generated.

[0166] By appropriately setting the operating force at this time, an increase start portion of the operating force formed by the cam portion 112 is a resistance applying portion 108, and it becomes possible to recognize a start position and the vicinity of the operation position of the increase range as a rotation finishing end of the operating member 104, with respect to the user of the operating member 104.

[0167] In addition, in FIG. 28B, a case where the displacement of the operating member 104 is adjusted to linearly increase with respect to the operation angle within the range that exceeds the operation position (θa) is illustrated, but a graph of the operation angle and the displacement within the range may be an appropriate right-upward graph in addition to a straight line.

[0168] In addition, in the example, the resistance applying portion 108 is formed by suddenly increasing the operating force, but a smooth increase within a range in which the user can recognize the rotation finishing end may be employed.

[0169] Therefore, in the example, in a normal state, the user can operate the operating member 104 as an operating range from the initial position to the operation position, and can perform the latch releasing operation in which the electric actuator is used by an inputting operation into the switch member 106 by the operation.

[0170] In addition, in a state where the latch releasing operation in which the electric actuator is used is not appropriately performed, when performing the rotation operation with respect to the operating member 104 further to emergency corresponding position at an operating force which is against the resistance applied by the resistance applying portion 108, it is possible to operate the cable device 102 via the follower body 113, and to perform the latch releasing of the door latch device 103.

[0171] In addition, above, a handle device in which the operating member 104 is linked to the fixed handle 115 in advance and which is fixed to the door 101 is described, but, the invention can also be employed in a handle device in which the base 115 is fixed to the rear surface of the door panel 119 in advance and the movable handle that provides a handle when performing the opening operation with respect to the door 101 is mounted on the base 115 from the front surface side of the door 101 as the operating member 104.
