If a fixture (not illustrated) is moved in the vertical and longitudinal directions (the arrows H, I, J and K) in a state where the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4 .[.is.]. .Iadd.are .Iaddend.provisionally fixed at the tailgate 3, the tailgate 3 is moved in the same direction.

(58) And, the fixing bolts BO of the tailgate 3 are inserted into through-holes 42e and 42d, respectively, and the attaching positions thereof are adjusted in the vertical and longitudinal directions of the arrows H, I, J and K in the respective adjustable ranges DA. Then, the tailgate 3 is matched to a prescribed position of the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4, and the fixing bolts BO are firmly tightened for regular tightening of the tailgate 3.

(59) And, the respective provisional fixing bolts (not illustrated) are removed from the through-holes 42f and 42g and the fixture is removed. As a result, the tailgate 3 is fixed in a state determined with respect to the gate opening portion 2d and the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4. As described above, since, only by adjusting the positions in the through-holes 42e and 42d, the tailgate 3 can be adjusted in terms of position with respect to the gate opening portion 2d of the vehicle body 2 and the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4 thereof, the number of steps of adjusting the positions is reduced, and the work can be simplified.

(60) The work for attaching the tailgate 3 on the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4 by the fixing .[.bolt.]. .Iadd.bolts .Iaddend.BO is carried out from the direction of the side plane .[.portion.]. .Iadd.portions 3a, .Iaddend.3a of the tailgate 3 with the tailgate 3 opened, wherein since the attaching point of the gate hinge .[.member.]. .Iadd.members 42, .Iaddend.42 by using the fixing .[.bolt.]. .Iadd.bolts .Iaddend.BO can be visually confirmed, the work can be easily earned out.

(61) Also, since work for attaching the .[.hinge.]. .Iadd.hinges 4, .Iaddend.4 to the tailgate 3 or detaching the same therefrom is carried out from the direction of the side plane .[.portion.]. .Iadd.portions 3a, .Iaddend.3a where any member hindering the work is not provided, the work can be smoothly carried out.

(62) Since the gate hinge .[.member.]. .Iadd.members 42, .Iaddend.42 .[.is.]. .Iadd.are .Iaddend.installed at the left and right side plane portions 3a and 3a of the tailgate 3, the supporting span between the hinge 4 on the left side plane portion 3a and the hinge 4 on the right side plane portion 3a is widened, wherein the retaining ability and rigidity of the tailgate 3 can be improved by means of the hinges 4 and 4.

(63) Further regarding the hinges 4 and 4, since the flat gate hinge members 42 and 42 are attached to the side plane portions 3a and 3a of the tailgate 3, the occupancy of the hinges 4 and 4 in the vehicle width direction is slight, wherein there is no case where the length L6 of the gate opening portion 2d in the width direction (Refer to FIG. 5) is limited. The length L6 of the gate opening portion 2d in the width direction (Refer to FIG. 5) is lengthened so as to widen the area, and thereby the loading and unloading work of loads can be facilitated.

(64) Also, as shown in FIG. 5, since, in the gate hinge .[.member.]. .Iadd.members 42, .Iaddend.42, the hinge base .[.member.]. .Iadd.members 41, .Iaddend.41 .[.is.]. .Iadd.are .Iaddend.installed in the .[.groove.]. .Iadd.grooves 2c, .Iaddend.2c on the roof portion 2b, and the gate hinge .[.member.]. .Iadd.members 42, .Iaddend.42 .[.is.]. .Iadd.are .Iaddend.installed at the side plane .[.portion.]. .Iadd.portions 3a, .Iaddend.3a of the tailgate 3, the hinge base .[.member.]. .Iadd.members 41, .Iaddend.41 and the gate hinge .[.member.]. .Iadd.members 42, .Iaddend.42 are not exposed to the luggage compartment 2h. Therefore, the appearance inside the luggage compartment 2h can be improved, and at the same time, clearance of the gate opening portion 2d and space in the luggage compartment 2h can be widened. Accordingly, loading of loads into the luggage compartment 2h and unloading thereof through the gate opening portion 2d can be easily carried out.

(65) Next, a description is given of actions of the rear part structure of a vehicle according to the first embodiment of the present invention.

(78) In FIG. 13, the roof .[.moulding.]. .Iadd.mouldings 113, .Iaddend.113 .[.is.]. .Iadd.are .Iaddend.fitted to the .[.portion.]. .Iadd.portions .Iaddend.forward of the .[.groove.]. .Iadd.grooves 108, .Iaddend.108, and when attaching the hinge .[.cover.]. .Iadd.covers 110, .Iaddend.110 composed of the above components before or after fitting the roof .[.moulding.]. .Iadd.mouldings 113, .Iaddend.113, the rear end of the roof .[.moulding.]. .Iadd.mouldings 113, .Iaddend.113 (FIG. 13) .[.is.]. .Iadd.are .Iaddend.placed between the narrow end .[.portion.]. .Iadd.portions 110a, .Iaddend.110a of the moulding .[.braid.]. connection .[.portion.]. .Iadd.portions 110d, .Iaddend.110d and the engagement tongue .[.portion.]. .Iadd.portions 110g, .Iaddend.110g in FIG. 14, and at the same time, the engagement .[.pin.]. .Iadd.pins 112, .Iaddend.112 .[.is.]. .Iadd.are .Iaddend.engaged in the engagement .[.hole.]. .Iadd.holes 105f, .Iaddend.105f, whereby when the hinge .[.cover.]. .Iadd.covers 110, .Iaddend.110 .[.is.]. .Iadd.are .Iaddend.attached to the rear .[.part.]. .Iadd.parts .Iaddend.of the .[.groove.]. .Iadd.grooves 108, .Iaddend.108 in FIG. 13, the upper .[.surface.]. .Iadd.surfaces .Iaddend.of the roof .[.moulding.]. .Iadd.mouldings 113, .Iaddend.113 .[.is.]. .Iadd.are .Iaddend.made flush with the upper .[.surface.]. .Iadd.surfaces .Iaddend.of the hinge .[.cover.]. .Iadd.covers 110, .Iaddend.110 to secure a smooth configuration.

(79) Now, as shown in FIG. 14, .Iadd.each of .Iaddend.the hinge .[.member.]. .Iadd.members .Iaddend.102 is composed of a turning arm portion 102a axially supported on the rotating axis 111 in the forward side of the vehicle and a gate supporting portion 102b formed to be integral with the turning arm portion 102a and becomes an attaching supporting portion of the tailgate 101. .[.The.]. .Iadd.Each .Iaddend.hinge member 102 is formed of, for example, a steel plate pressed article, and in the present embodiment, it is formed to be a roughly flat plate-shaped member. The plate surface thereof extends .[.almost on the.]. .Iadd.along a respective .Iaddend.plane .[.including.]. .Iadd.parallel to .Iaddend.the opening and closing directions of the tailgate 101, that is, a .[.perpendicular.]. plane .[.along.]. .Iadd.parallel to .Iaddend.the longitudinal direction of the vehicle.

(80) In the tailgate 101, as shown in FIG. 13, the side plane .[.portion.]. .Iadd.portions 101a, .Iaddend.101a .[.is.]. .Iadd.are .Iaddend.formed in the vicinity of the left and right edge portions at the plane side facing the inside of the vehicle compartment so that .[.it is erected.]. .Iadd.they extend .Iaddend.toward the inside of the compartment and along the vertical direction of the tailgate 101. (In FIG. 13, only the right side plane portion 101a is shown). The tailgate 101 is attached in the form that .[.the.]. .Iadd.each .Iaddend.side plane portion 101a is brought into facial contact with the gate supporting portion 102b of the .Iadd.corresponding .Iaddend.hinge member 102. Concretely speaking, as shown in FIG. 15, .[.the.]. .Iadd.each .Iaddend.hinge member 102 is slightly bent and formed so that it becomes roughly elbow-shaped in its side view, and the recess portion side thereof is disposed so as to face the inside of the compartment, wherein .[.the.]. .Iadd.each .Iaddend.gate supporting portion 102b is connected to the upper part of the .Iadd.corresponding .Iaddend.side plane portion 101a of the tailgate 101.

(81) As shown in FIG. 15A, .Iadd.the gate supporting portion 102b of each hinge member 102 includes .Iaddend.a gate attaching portion 121 which is positioned at the upper edge side of the tailgate 101 and a gate attaching portion 122 which is positioned downward of the gate attaching portion 121 .[.are provided in the gate supporting portion 102b.]. with the tailgate 101 fully closed. With the tailgate 101 fully closed, the gate attaching portions 121 and 122 are positioned downward of the rotating axis 111, and in the present embodiment, these components are located at the rearward side of the vehicle more than the rotating axis 111 .Iadd.of the corresponding hinge member 102.Iaddend.. Further, in the embodiment, the gate attaching portions 121 and 122 are formed as gate attaching holes that pass through in the width direction of the vehicle, whereby the tailgate 101 is connected to and fixed at the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 by fixing bolts (not illustrated) in the .[.portion.]. .Iadd.portions .Iaddend.of the side plane .[.portion.]. .Iadd.portions 101a, .Iaddend.101a thereof via the respective gate attaching portions 121 and 122 formed as holes. Further, insertion holes 123 and 124 of bolts for provisionally fixing a fixture (not illustrated) used to attach the tailgate 101 are drilled between both the gate attaching portions 121 and 122.

(82) The present invention is mainly featured in that, in a state where the tailgate 101 shown in FIG. 15A is closed, the positions of the gate attaching portions 121 and 122 of the hinge member 102 at the side where the open stay 103 (FIG. 13) is provided are set downward of the positions of the gate attaching portions 121 and 122 of the other hinge member 102. FIGS. 15(a).[.,.]. .Iadd.and .Iaddend.15(b) are views.Iadd., partly in cross section, .Iaddend.showing a side section of the vehicle as described above. Therefore, in .[.the.]. .Iadd.these side .Iaddend.views, .[.it seems that.]. the pair of hinge members 102 .Iadd.appear to .Iaddend.overlap each other. Therefore, in the following description, a description is based on the hinge member 102 shown in FIG. 15(a) (that is, this is a hinge member positioned at the left side of a vehicle, which is the hinge member at the side where the open stay 103 (FIG. 13) is not provided) being given a reference number 102A, the distance dimensions thereof are given reference numbers L7 and L9 while the hinge member 102 positioned at the deep side of the paper (that is, this is a hinge member positioned at the right side of the vehicle, which is the hinge member at the side where the open stay 103 is provided) is given a reference number 102B and the distance dimensions thereof are given reference numbers L8 and L10.

(83) The distance dimensions L8 and L10 with respect to the perpendicular direction between the center of the rotating axis in the hinge member 102B and the respective gate attaching portions 121 and 122 (respectively indicating the center of the hole) are set to greater values than the same distance dimensions L7 and L9 in the hinge member 102A. That is, since the positions of the rotating axes 111 in both the hinge members 102A and 102B are set to the same height, the positions of the gate attaching portions 121 and 122 of the hinge member 102B are located downward of the positions of the gate attaching portions 121 and 122 of the hinge member 102A. In the present embodiment, for example, the distance dimensions L8 and L10 at the hinge member 102B side are, respectively, set to 23.1 mm and 79.4 mm while those L7 and L9 at the hinge member 102A side are, respectively, set to 22.5 min and 78.7 mm. That is, the respective hinge members 102A and 102B are formed so that dimensional differences are produced by 0.6 mm at the gate attaching portion 121 and by 0.7 mm at the gate attaching portion 122.

(84) Thus, if, with the tailgate 101 closed, the hole positions of the gate attaching portions 121 and 122 at the hinge member 102B side are set to be lower than the hole positions of the other side, and are set to so-called left-right asymmetrical hole positions, it is possible, in an assembling process of the open stay 103, to absorb a deviation error without requiring any adjustment work, for example, by using a shim, etc., with respect to correction of the deviation between the left and right sides of the tailgate 101, which results from a reaction from the open stay 103, in detail, a deflection at the side where the open stay 103 is not provided. Therefore, when assembling the tailgate 101 in the vehicle body 104 or attaching the open stay 103, no adjustment work is required, wherein working efficiency can be improved.

(85) Also, if, for example, the through-holes of the gate attaching portions 121 and 122 are drilled as holes which are slightly greater than the fixing bolts (not illustrated), and the hinge member 102 is composed so that it is adjustable in the longitudinal and vertical directions of the vehicle with respect to the tailgate 101, it is possible to improve the assembling accuracy of the hinge member 102 and tailgate 101 with simple work.

(86) Also, if the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 .[.is.]. .Iadd.are .Iaddend.shaped so as to extend along .[.the plane including.]. .Iadd.respective planes parallel to .Iaddend.the opening and closing directions of the tailgate 101 and the gate attaching portions 121 and 122 are formed as gate attaching holes passing through in the width direction of the vehicle, an opening and closing load operates on the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 in .[.its.]. .Iadd.their .Iaddend.extending plane .[.direction.]. .Iadd.directions .Iaddend.when the tailgate 101 is opened and closed. Therefore, it is possible to secure strength against the opening and closing load. Accordingly, the outer shape and plate thickness of the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 can be reduced, wherein weight and production costs can be reduced.

(87) Further, by attaching the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 to the side plane .[.portion.]. .Iadd.portions 101a, .Iaddend.101a of the tailgate 101, assembling work of the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 can be carried out at a lateral position of the tailgate 101, which becomes an open space, wherein the assembling work can be easily carried out, and the detailed attaching point of .[.the.]. .Iadd.each .Iaddend.hinge member 102 with respect to the tailgate 101 can be visually confirmed. In addition, such a structure can be obtained, in which, when the tailgate 101 is opened and closed, a force is .[.added.]. .Iadd.applied .Iaddend.to the fixing .[.portion.]. .Iadd.portions .Iaddend.of the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 and the side plane .[.portion.]. .Iadd.portions 101a, .Iaddend.101a not in the direction along which the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 .[.is.]. .Iadd.are .Iaddend.peeled off from the tailgate 101 but in the shearing direction thereof. Therefore, it is possible to obtain large fixing strength by tightening means such as bolts.

(88) Also, if such a structure is employed, in which the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 .[.is.]. .Iadd.are .Iaddend.provided in the .[.groove.]. .Iadd.grooves 108, .Iaddend.108 which .[.is.]. .Iadd.are .Iaddend.recessed with respect to the roof panel R, it is possible to prevent the attaching .[.portion.]. .Iadd.portions .Iaddend.of the hinge .[.member.]. .Iadd.members 102, .Iaddend.102 from protruding from the roof panel R. In this case, for example, as in the present embodiment, by attaching the hinge .[.cover.]. .Iadd.covers 110, .Iaddend.110 to the .[.groove.]. .Iadd.grooves 108, .Iaddend.108, it is possible to cover up the attaching portion of .[.the.]. .Iadd.each .Iaddend.hinge member 102, wherein appearance design thereof can be improved.
