DETAILED DESCRIPTION OF EMBODIMENTS

(10) In one aspect of this technology, the window glass may be configured to be movable to an opening direction where the opening is to be opened and to a closing direction where the opening is to be closed. In this case, the belt molding may be placed on the opening-direction side relative to the opening and may slidably make contact with the outer surface of the window glass. In such a configuration, the belt molding easily deteriorates due to sliding with the window glass. Accordingly, the present technology that achieves easy replacement of the belt molding can be preferably employed. Note that, in other aspects, the belt molding may make contact with the outer surface of fixed window glass.

(11) In one aspect of this technology, the base member may be bonded to the inner surface of the outer panel by a double-stick tape. Hereby, in a stage where the vehicle is manufactured, the belt molding can be relatively easily bonded to the inner surface of the outer panel.

(12) In one aspect of this technology, the base member may include a plurality of bosses extending inwardly in the vehicle width direction from the attachment surface, the bosses being placed at respective positions corresponding to the fixed points. In this case, the belt molding body may have a plurality of holes such that the bosses are passed through the holes, respectively. With such a configuration, by use of the bosses of the base member and the holes of the belt molding body, the belt molding body can be relatively easily fixed to the base member.

(13) In the above aspect, the bosses may be fitted within the holes at the fixed points. Hereby, the belt molding body can be hardly detached from the base member, and the belt molding body is stably fixed to the base member.

(14) In the above aspect, each of the bosses may include a diameter-increased portion having a diameter larger than a diameter of a corresponding one of the holes, the diameter-increased portion being provided in a distal end of the each of the bosses. With such a configuration, the diameter-increased portion makes it possible to prevent the each of the bosses from coming out of its corresponding hole. That is, the belt molding body is firmly fixed to the base member.

(15) In one aspect of this technology, the belt molding body may be welded to the base member at each of the fixed points. Hereby, the belt molding body can be hardly detached from the base member.

(16) In one aspect of this technology, the base member may include a rim abutting with the upper end or lower end of the belt molding body in the vehicle up-down direction. Hereby, at the time when a new belt molding body is attached to the base member, the position of the belt molding body can be hardly displaced from the base member.

(17) In one aspect of this technology, the base member may be made of a material having a rigidity higher than the rigidity of a material constituting the belt molding body. Hereby, the outer surface of the outer panel can hardly deform at the time when the deteriorated belt molding body is detached from the base member.

(18) In the above aspect, the base member may be made of a resin material, and the belt molding body may be made of a rubber material. The rubber material is one of materials having an appropriate elasticity to seal a gap between the window glass and the outer panel. The rubber material may be natural rubber or synthetic rubber. Note that the rubber material used herein includes a material called elastomer.

That is, in the peripheral edge of the first window opening 28a, the first window glass 23f faces the window frame 22, the first sash bar 24, and the outer panel 21. The first window glass 23f is window glass that is not openable and closable, and the first window glass 23f is fixed to the window frame 22 and the first sash bar 24. The first window glass 23f closes the first window opening 28a.

(25) The second window opening 28b is placed in the middle among the three window openings 28a, 28b, 28c and is surrounded by the window frame 22, the two sash bars 24, 26, and the outer panel 21. Second window glass 25 is provided in the second window opening 28b. That is, in the peripheral edge of the second window opening 28b, the second window glass 25 faces the window frame 22, the two sash bars 24, 26, and the outer panel 21. The second window glass 25 is window glass that is openable and closable. The second window glass 25 is attached movably along the two sash bars 24, 26. The second window glass 25 closes the second window opening 28b.

(26) The third window opening 28c placed most rearward among the three window openings 28a, 28b, 28c is surrounded by the window frame 22, the second sash bar 26, and the outer panel 21. Third window glass 23r is provided in the third window opening 28c. That is, in the peripheral edge of the third window opening 28c, the third window glass 23r faces the window frame 22, the second sash bar 26, and the outer panel 21. The third window glass 23r is window glass that is not openable and closable, and the third window glass 23r is fixed to the window frame 22 and the second sash bar 26. The third window glass 23r closes the third window opening 28c. Here, each window glass 23f, 25, 23r is not limited to glass and may be constituted by other transparent or translucent materials such as acryl resin, for example.

(27) FIGS. 2, 3 are front views of the door 20. That is, FIGS. 2, 3 illustrate the shape of the door 20 when the door 20 is viewed from the inside of a vehicle cabin along the right-left direction of the vehicle 10. As illustrated in FIGS. 2, 3, the second window glass 25 is operated directly by the user to move in the up-down direction between an upper limit position at which the second window glass 25 closes the second window opening 28b and a lower limit position at which the second window glass 25 opens the second window opening 28b. As illustrated in FIG. 2, when the second window glass 25 moves in an opening direction Od from the upper limit position of the second window glass 25, the second window opening 28b is opened. As illustrated in FIG. 3, when the second window glass 25 moves in a closing direction Cd from the lower limit position of the second window glass 25, the second window opening 28b is closed. The opposite ends of the second window glass 25 in the vehicle front-rear direction are slidably supported by the two sash bars 24, 26. The second window glass 25 moves in the vehicle up-down direction along the two sash bars 24, 26.

(28) A knob 60 to be gripped by the user is provided in the second window glass 25. The knob 60 is attached to the inner surface of the second window glass 25 (that is, a surface thereof on the near side of the plane of paper of FIG. 2), and the knob 60 projects from the inner surface of the second window glass 25. The user can easily operate the second window glass 25 by use of the knob 60 from the inside of the vehicle cabin. That is, the user can raise the second window glass 25 by gripping the knob 60 or can lower the second window glass 25 by gripping the knob 60. That is, the second window glass 25 is operated in the up-down direction directly by the user without the use of a mechanism such as a conventional raising-lowering device, for example. Note that the second window glass 25 may be moved in the up-down direction by the conventional raising-lowering device.

(29) The knob 60 is provided with a movable hook 62 to be operated by the user. Meanwhile, the window frame 22 is provided with a hook receiver 64 corresponding to the hook 62. When the second window glass 25 is placed at the upper limit position, the hook receiver 64 engages with the hook 62. Hereby, the second window glass 25 placed at the upper limit position is locked so that the second window glass 25 does not move down by deadweight, for example. Here, the positions of the knob 60, the hook 62, and the hook receiver 64 are not limited in particular. For example, the knob 60 and the hook 62 may be provided at different positions. Alternatively, the hook 62 may be provided in the window frame 22 while the hook receiver 64 may be provided in the second window glass 25.

(30) As illustrated in FIGS. 2, 3, a door trim 29 is placed below the three window openings 28a, 28b, 28c. The door trim 29 includes an inside handle 29h and a speaker grille 29s. The door trim 29 is a component decorating the inner surface of the door 20. The door trim 29 improves the design property (that is, the outward appearance) of the door 20 viewed from the inside of the vehicle cabin by covering the inner side of the door 20. The door trim 29 is mainly made of resin. The inside handle 29h is a handle to be operated by the user so that the user opens the door 20 from inside the vehicle. The speaker grille 29s has a plurality of through-holes on its surface. Sound emitted from a speaker (not shown) housed inside the door 20 reaches the user inside the vehicle cabin through the speaker grille 29s.

(31) When the second window glass 25 is moved in the opening direction Od such that the second window glass 25 is placed at the lower limit position, a space between the knob 60 and the door trim 29 becomes small as illustrated in FIG. 3. A recess 29l is provided in an upper part of the door trim 29. The knob 60 placed at the lower limit position faces the recess 29l.

(32) With reference to FIG. 4, the following describes a structure of an upper end part of the outer panel 21. FIG. 4 is a sectional view taken along a line IV-IV in FIG. 3. That is, FIG. 4 is a sectional view in the lower peripheral edge of the second window opening 28b. As described with reference to FIG. 2, the second window glass 25 is moved in the opening direction Od to open the second window opening 28b. That is, FIG. 4 is a sectional view in a peripheral edge of the second window opening 28b on the opening direction Od side.

(33) The recess 29l is provided in the upper part of the door trim 29. The recess 29l forms a space that receives the hand of the user that operates the knob 60 between the recess 29l and the knob 60. Further, an inner panel 27, an inner reinforcement 27r, and an inner weather strip 27w are placed inside the door trim 29. The inner panel 27 is a sheet metal part provided on the inner side of the door 20 (see FIG. 2) in the vehicle width direction, and the door trim 29 is fixed to the inner panel 27. The inner reinforcement 27r is a sheet metal part configured to partially reinforce the inner panel 27. The inner weather strip 27w is fixed by being put to the upper ends of the inner panel 27 and the inner reinforcement 27r. The inner weather strip 27w seals a gap between the inner panel 27 and the inner surface of the second window glass 25.

(34) An outer panel 21 is placed to the right side of the second window glass 25 (that is, the outer side of the second window glass 25 in the vehicle width direction). FIG. 4 is a sectional view in the peripheral edge of the second window opening 28b on the opening direction Od side as described earlier. The outer panel 21 faces the second window glass 25 in the peripheral edge of the second window opening 28b on the opening direction Od side. A belt molding 30 is placed in an upper end part of an inner surface 21i of the outer panel 21. The belt molding 30 is fixed to the inner surface 21i of the outer panel 21 by a double-stick tape 32. The belt molding 30 includes a base member 34 and a belt molding body 30b. The base member 34 is made of a resin material. The base member 34 has a flat shape extending in the up-down direction, and the bottom end of the base member 34 bends to the left side (that is, inwardly in the vehicle width direction). The right surface of the base member 34 (that is, the outer surface thereof in the vehicle width direction) is fixed to the inner surface 21i of the outer panel 21 by the double-stick tape 32. The left surface of the base member 34 (that is, the inner surface thereof in the vehicle width direction) is provided with an attachment surface 34p facing the outer surface of the second window glass 25. The belt molding body 30b is fixed to the attachment surface 34p of the base member 34. A detailed structure to fix the belt molding body 30b to the base member 34 will be described later. Note that the belt molding 30 extends in the front-rear direction with a uniform sectional shape along the upper end part of the outer panel 21. In the lower peripheral edge of the first window opening 28a, the belt molding 30 seals a gap between the outer surface of the first window glass 23f and the outer panel 21. In the lower peripheral edge of the third window opening 28c, the belt molding 30 seals a gap between the outer surface of the third window glass 23r and the outer panel 21. Similarly to the gap between the outer panel 21 and the second window glass 25 that is openable and closable, the belt molding 30 also seals the gap between the outer panel 21 and each of the first window glass 23f and the third window glass 23r that are not openable and closable.

(35) The belt molding body 30b is typically made of a rubber material. As described earlier, the base member 34 is made of a resin material. That is, the base member 34 is made of a resin material having a rigidity higher than the rigidity of the rubber material constituting the belt molding body 30b. The belt molding body 30b includes two lips extending toward the outer surface of the second window glass 25. The two lips of the belt molding body 30b elastically deform by abutting with the outer surface of the second window glass 25 and seal the gap between the second window glass 25 and the outer panel 21. The rubber material may be natural rubber or synthetic rubber. Note that the rubber material used herein includes a material called elastomer. Flocking (not shown) is performed on respective surfaces of the lips of the belt molding body 30b. Flocked parts of the belt molding body 30b abut with the outer surface of the second window glass 25. When the flocked parts of the belt molding body 30b abut with the outer surface of the second window glass 25, a frictional force to be caused between the outer surface of the second window glass 25 and the belt molding body 30b is reduced. As a result, the second window glass 25 smoothly moves on the surfaces of the lips of the belt molding body 30b. Thus, the belt molding body 30b slidably makes contact with the outer surface of the second window glass 25.

(36) The detailed structure to fix the belt molding body 30b to the base member 34 will be described with reference to FIGS. 5, 6. FIG. 5 is a perspective view illustrating the belt molding body 30b, the base member 34, and the double-stick tape 32 in an exploded manner. As illustrated in FIG. 5, the base member 34 includes a plurality of bosses 34b provided such that the bosses 34b are distanced from each other and extend to the left side (that is, inwardly in the vehicle width direction) from the attachment surface 34p. The base member 34 includes a rim 34r extending in the front-rear direction. The rim 34r is provided in a lower end part of the base member 34. Further, the belt molding body 30b has a plurality of holes 30h such that the holes 30h are provided at respective positions facing the bosses 34b of the base member 34 and distanced from each other. As illustrated in FIG. 5, each of the bosses 34b of the base member 34 is inserted into its corresponding hole 30h in the belt molding body 30b. As a result, each of the bosses 34b is passed through its corresponding hole 30h. Note that, in FIG. 5, a reference sign is assigned only to the boss 34b placed on the rightmost side (that is, the rear side in the vehicle front-rear direction) in FIG. 5 among the bosses 34b, and no reference sign is assigned to the other bosses 34b. Similarly, in FIG. 5, a reference sign is assigned only to the hole 30h placed on the rearmost side, and no reference sign is assigned to the other holes 30h.

(37) After the boss 34b of the base member 34 is passed through the hole 30h of the belt molding body 30b, the distal end of the boss 34b is melted from the left side by use of an ultrasonic wave jig (not shown). Hereby, as illustrated in FIG. 6, the height of the boss 34b is reduced while the diameter of the boss 34b is increased. As a result, a diameter-increased portion 34m is formed in the distal end of the boss 34b. The diameter of the diameter-increased portion 34m is larger than the diameter of the hole 30h of the belt molding body 30b. On this account, the belt molding body 30b is not detached from the base member 34. Note that, at the time when the distal end of the boss 34b is melted, the left surface of the belt molding body 30b may be or may not be melted together with the distal end of the boss 34b so as to be welded to the diameter-increased portion 30m. As illustrated in FIG. 6, the belt molding body 30b is fixed to the attachment surface 34p of the base member 34 such that the diameter-increased portion 34m of the boss 34b abuts with (or is welded to) a peripheral edge part of the hole 30h. The other parts of the belt molding body 30b are not fixed to the attachment surface 34p. That is, the belt molding body 30b is fixed to the attachment surface 34p with a relatively small area as an abutment part between the diameter-increased portion 34m of the boss 34b and the peripheral edge part of the hole 30h. That is, the belt molding body 30b is supported on the attachment surface 34p of the base member 34 via a fixed point 30p. In FIG. 6, the center of the abutment part between the diameter-increased portion 34m of the boss 34b and the peripheral edge part of the hole 30h is expressed as the fixed point 30p. As has been described with reference to FIG. 5, the base member 34 includes the bosses 34b distanced from each other, and the belt molding body 30b has the holes 30h corresponding to the bosses 34b distanced from each other. The belt molding body 30b is also supported by the bosses 34b and their corresponding holes 30h via the fixed points 30p. That is, the belt molding body 30b is supported on the attachment surface 34p via the fixed points 30p distanced from each other.

(38) When respective distal ends of the bosses 34b are all melted, and the belt molding body 30b is fixed to the base member 34, the belt molding 30 is completed. As illustrated in FIGS. 5, 6, the belt molding 30 thus completed is bonded to the inner surface 21i of the outer panel 21 by the double-stick tape 32. Hereby, the belt molding 30 is fixed to the inner surface 21i of the outer panel 21 made of resin. Note that the belt molding 30 may be bonded to the inner surface 21i by an adhesive agent.

(39) As has been described with reference to FIG. 4, the belt molding 30 seals the gap between the outer surface of the second window glass 25 and the outer panel 21. The sealing property of the belt molding 30 decreases along with deterioration of the belt molding 30. Particularly, the belt molding body 30b easily deteriorates materially and markedly decreases the sealing property of the belt molding 30 along with the deterioration. Since the belt molding body 30b is exposed to outside the vehicle, foreign materials such as rain water and dust attached to the outer surface of the second window glass 25 are easily attached to the belt molding body 30b. These foreign materials advance the deterioration of the belt molding body 30b. Further, deteriorations such as abrasion caused due to sliding of the second window glass 25 also occur in the belt molding body 30b. On this account, the belt molding body 30b is a member that easily deteriorates, and therefore, it can be presumed that the belt molding body 30b needs to be replaced earlier than the life of the vehicle 10 (or the vehicle door 20).

(40) As described earlier, the belt molding body 30b is supported by the base member 34 via the fixed points 30p distanced from each other. Accordingly, at the time when the deteriorated belt molding body 30b is detached, the belt molding body 30b can be easily detached by cutting the diameter-increased portions 30m at the fixed points 30p. After that, the bosses 34b are cut from their bottoms, and the surface of the attachment surface 34p is smoothed off. A new belt molding body 30b is fixed by a double-stick tape to the attachment surface 34p from which the bosses 34b have been removed by cutting. Hereby, the belt molding body 30b can be easily replaced without deforming the outer surface of the outer panel 21. Note that, generally, re-replacement of the new belt molding body 30b is presumed to be required after the life of the vehicle 10 (or the door 20). On this account, a double-stick tape may be employed to fix the new belt molding body 30b. Further, as illustrated in FIG. 6, the lower end of the belt molding body 30b abuts with the upper surface of the rim 34r of the base member 34. Accordingly, at the time when the new belt molding body 30b is fixed to the attachment surface 34p from which the bosses 34b have been removed, the position of the belt molding body 30b can be hardly displaced. Note that the rim 34r may be formed in an upper end part of the base member 34, or respective rims 34r may be formed in opposite end parts of the base member 34 such that the rims 34r face each other via the belt molding body 30b.

(41) With reference to FIG. 7, the following describes a structure in which a belt molding body 40b of a belt molding 40 according to a second embodiment is supported on an attachment surface 44p of a base member 44. The base member 44 of the belt molding 40 according to the second embodiment does not include bosses on the attachment surface 44p. No hole is formed in the belt molding body 40b. In the second embodiment, the attachment surface 44p is directly welded to the right surface of the belt molding body 40b (that is, the outer surface thereof in the vehicle width direction). In the second embodiment, in a state where the attachment surface 44p is brought into contact with the belt molding body 40b, ultrasonic waves are applied to a central part between the attachment surface 44p and the belt molding body 40b from the opposite sides across the central part, so that the attachment surface 44p is welded to the belt molding body 40b. As a result, a mixture portion 40m is formed. In the mixture portion 40m, a resin material of the attachment surface 44p and a rubber material of the belt molding body 40b are mixed and solidified. The mixture portion 40m fixes the belt molding body 40b to the attachment surface 44p of the base member 44. That is, the belt molding body 40b is fixed to the attachment surface 44p with a relatively small area as the mixture portion 40m. That is, the belt molding body 40b is supported on the attachment surface 44p at a fixed point 40p. In FIG. 7, the center of the mixture portion 40m is expressed as the fixed point 40p. In the belt molding 40 of the second embodiment, the mixture portions 40m are formed at predetermined pitches along the front-rear direction of the belt molding 40. That is, the belt molding body 40b is supported on the attachment surface 44p of the base member 44 via the fixed points 40p distanced from each other. With such a configuration, when the belt molding body 40b deteriorates, the deteriorated belt molding body 40b can be easily detached by cutting the mixture portions 40m.

(42) With reference to FIG. 8, the following describes a structure in which a belt molding body 50b of a belt molding 50 according to a third embodiment is supported on an attachment surface 54p of a base member 54. The base member 54 includes bosses 54b extending to the left side (that is, inwardly in the vehicle width direction) from the attachment surface 54p. The belt molding body 50b includes holes 50h through which the bosses 54b are passed. Differently from the first embodiment described with reference to FIG. 6, the diameter of the boss 54b according to the third embodiment is larger than the diameter of the hole 50h. Accordingly, when the boss 54b is fitted to the hole 50h by pressing, the boss 54b is fitted within the hole 50h. As a result, the belt molding body 50b is fixed to the attachment surface 54p of the base member 54. That is, the belt molding body 50b is fixed to the attachment surface 54p with a relatively small area as an abutment part between the side face of the boss 54b and the inner peripheral surface of the hole 50h. That is, the belt molding body 50b is supported on the attachment surface 54p of the base member 54 via a fixed point 50p. In FIG. 8, the center of a part where the boss 54b is fitted within the hole 50h is expressed as the fixed point 50p. Similarly to the belt molding 30 according to the first embodiment described with reference to FIG. 5, the belt molding 50 according to the third embodiment is also configured such that the bosses 54b distanced from each other are passed through their corresponding holes 50h, respectively. That is, the belt molding body 50b is supported on the attachment surface 54p via the fixed points 50p distanced from each other. With such a configuration, when the belt molding body 50b deteriorates, the deteriorated belt molding body 50b can be easily detached by cutting the bosses 54b. Note that the distal end of the boss 54b may be provided with a detent, and the belt molding body 50b may be supported on the attachment surface 54p such that the detent is fitted within the hole 50h.
