[0001] The present disclosure relates to a glass run for an automobile door that is disposed on a window frame of an automobile door, and to an assembly method for assembling a molding to the outer side of the glass run. [Background technology]

[0002] For example, Patent Document 1 discloses a glass run that is attached to a window frame from the outside of the vehicle. The glass run in Patent Document 1 includes an upper edge of the glass run that extends in the front-to-rear direction along the side edge of the roof of the vehicle, and a molding that is attached to the outside of the glass run upper edge. On the outside of the vehicle of the glass run upper edge, a fitting portion into which the molding fits is formed in the shape of a rail that continues in the front-to-rear direction. Meanwhile, a positioning member called an end cap is fixed to the rear end of the molding. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2019-112010 A Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, when assembling the molding to the upper edge portion of the glass run, the front end portion of the molding is fitted into the rear end portion of the fitting portion of the upper edge portion of the glass run, and then the molding is moved forward relative to the upper edge portion of the glass run.

[0005] The assembly of the molding to the upper edge of the glass run will be described in detail with reference to FIG. 9. FIG. 9 corresponds to FIG. 7 of Patent Document 1, and shows a cross section of the upper edge 11 of the glass run and the molding 30 cut horizontally. FIG. 9A is a cross section of the rear end of the upper edge 11 of the glass run and the molding 30 in the middle of assembling the molding 30, FIG. 9B is a cross section of the front end of the upper edge 11 of the glass run and the molding 30 in the middle of assembling the molding 30, FIG. 9C is a cross section of the rear end of the upper edge 11 of the glass run and the molding 30 in the state where the assembly of the molding 30 is completed, and FIG. 9D is a cross section of the front end of the upper edge 11 of the glass run and the molding 30 in the state where the assembly of the molding 30 is completed. The arrow A in each figure indicates the assembly direction of the molding 30, that is, the relative movement direction of the molding 30 with respect to the upper edge 11 of the glass run.

[0006] As described in Patent Document 1, a positioning member 34 is fixed to the rear end of the molding 30, and a locking portion 34c is provided at the rear end of the positioning member 34 so as to protrude forward. Meanwhile, an insertion hole 58 into which the locking portion 34c can be inserted is formed at the rear end of the glass run upper side portion 11. When the molding 30 is moved in the assembly direction as shown in FIG. 9A, the locking portion 34c is inserted into the insertion hole 58 as shown in FIG. 9C, completing the assembly. As a result, the rear end of the molding 30 is fixed to the glass run upper side portion 11 via the positioning member 34.

[0007] 9B and 9D. The front end of the molding 30 also needs to be fixed to the glass run upper side portion 11, but a positioning member 34 similar to that at the rear end cannot be provided. In other words, because the direction of movement of the molding 30 is the forward direction, it is impossible to insert a locking portion 34c like that at the rear end into the glass run upper side portion 11 during the assembly operation. For this reason, a structure is required in which member B provided at the front end of the molding 30 is fixed to the glass run upper side portion 11 using double-sided tape C.

[0008] However, when using double-sided tape, many steps are required, such as applying a primer to the adhesive surface of the molding 30, applying a primer to the adhesive surface of the glass run upper edge portion 11, attaching the double-sided tape to the glass run upper edge portion 11, removing the release paper from the double-sided tape, and pressing, which reduces workability and increases the number of work steps. Furthermore, the adhesive strength of the double-sided tape may decrease over time or due to the external environment, causing the front end of the molding 30 to lift off the glass run upper edge portion 11, deteriorating the appearance.

[0009] The present disclosure has been made in consideration of such points, and its object is to improve the ease of assembly of the molding to the glass run and reduce the amount of work required, while suppressing deterioration of the external appearance due to aging or the external environment. [Means for solving the problem]

[0010] In order to achieve the above object, one aspect of the present disclosure can be premised on a molding assembly method for assembling a molding extending in the vehicle front-rear direction to the vehicle outer side of an upper edge part of a glass run for an automobile door that extends in the vehicle front-rear direction of the vehicle in a glass run that is assembled to a window frame from the vehicle exterior side. The molding assembly method includes a glass run forming step of forming a main body side fitting part extending in the vehicle front-rear direction on the vehicle exterior side of the upper edge part of the glass run, a fixing step of fixing a first positioning member having a first locking part protruding toward the other end of the molding in the vehicle front-rear direction, and a step of fitting a molding side fitting part formed at the other end of the molding in the vehicle front-rear direction to which the first positioning member is fixed, into one end of the main body side fitting part in the vehicle front-rear direction, and then moving the molding in the other vehicle front-rear direction relative to the glass run upper edge part. the first engagement step of inserting the first engagement portion into a first insertion hole formed on one side of the upper edge portion of the glass run in the fore-and-aft direction of the vehicle by the relative movement and engaging it with the peripheral portion of the first insertion hole; and after the moving step, a second positioning member having a second engagement portion protruding toward one side is fixed to the other end of the molding in the fore-and-aft direction of the vehicle, and the second engagement portion is inserted into a second insertion hole formed on the other side of the upper edge portion of the glass run in the fore-and-aft direction of the vehicle and engaged with the peripheral portion of the second insertion hole.

[0011] According to this configuration, when the molding is assembled by moving it relatively in the vehicle front-rear direction with respect to the upper edge of the glass run, the first locking portion of the first positioning member fixed to the molding is inserted into the first insertion hole of the upper edge of the glass run, thereby locking the molding to the periphery of the first insertion hole. As a result, one end of the molding in the vehicle front-rear direction is fixed to the upper edge of the glass run via the first positioning member.

[0012] On the other hand, for the other end of the molding in the vehicle front-rear direction, the second positioning member is fixed after the molding moving process, and the second locking portion is inserted into the second insertion hole in the upper edge portion of the glass run, so that the second locking portion is locked to the periphery of the second insertion hole. As a result, the other end of the molding in the vehicle front-rear direction is fixed to the upper edge portion of the glass run via the second positioning member.

[0013] Therefore, both ends of the molding in the fore-and-aft direction of the vehicle can be fixed to the upper edge of the glass run without using double-sided tape as in the conventional example, eliminating the need for many processes such as applying primer, applying double-sided tape, removing the release paper, and pressing, and also suppressing the molding from lifting up over time or due to the external environment.

[0014] In the second locking step, the second positioning member can be fixed to the molding by elastically deforming a claw portion formed on the second positioning member and hooking it into a notch portion formed in the molding. This allows the second positioning member to be easily fixed to the molding without using tools or the like. The claw portion and the notch portion can also be formed on both the upper and lower sides, which stabilizes the second positioning member relative to the molding.

[0015] In the second locking process, the fixing plate portion of the second positioning member is inserted between the interior surface of the molding and the exterior surface of the upper edge portion of the glass run from the other side in the fore-and-aft direction of the vehicle, and the second locking portion formed on the interior side of the vehicle relative to the fixing plate portion of the second positioning member can be inserted into the second insertion hole. Effect of the Invention

[0016] As described above, when assembling the molding by moving it relatively in the fore-and-aft direction of the vehicle with respect to the upper edge of the glass run, both ends of the molding in the fore-and-aft direction of the vehicle can be fixed to the upper edge of the glass run without using double-sided tape, which improves the ease of assembling the molding and reduces the amount of labor required for assembly. Moreover, deterioration of the appearance due to aging or the external environment is suppressed, and a good appearance can be maintained for a long period of time.

[0018] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its applications, or its uses.

[0019] FIG. 1 is a right side view of an automobile 100 according to an embodiment of the present invention. A front door 101 and a rear door 102 are provided on the left and right sides of the automobile 100. The front end of each of the front door 101 and the rear door 102 is rotatably attached to the vehicle body via a hinge (not shown). In this embodiment, the present invention is described as being applied to the rear door 102, but is not limited to this, and can also be applied to the front door 101. The present invention can also be applied to either the left or right door 101, 102. In the description of this embodiment, the front side of the vehicle will be simply referred to as the "front" and the rear side of the vehicle will be simply referred to as the "rear".

[0020] (Rear door configuration) The rear door 102 is equipped with a glass run for an automobile door (hereinafter, simply referred to as a glass run) 10. The rear door 102 has a door body 103 constituting approximately the lower half of the rear door 102, and a window frame 104 constituting approximately the upper half, and the rear door 102 is provided with a window glass G that can be raised and lowered.

[0021] The window frame 104 is a frame-like member that supports the periphery of the window glass G and forms an opening 108 for the window glass. The window frame 104 has a front frame vertical side portion 104a, a rear frame vertical side portion 104b, and a frame upper side portion 104c. The front frame vertical side portion 104a extends in the vertical direction at the front of the rear door 102. The rear frame vertical side portion 104b extends in the vertical direction at the rear of the rear door 102. The lower portions of the front frame vertical side portion 104a and the rear frame vertical side portion 104b reach the inside of the door body 103, so that the window glass G can be guided to the inside of the door body 103 when it is lowered. The frame upper side portion 104c extends from the upper end of the front frame vertical side portion 104a to the upper end of the rear frame vertical side portion 104b, and is inclined so as to be positioned lower toward the rear in accordance with the shape of the window glass G.

[0022] 3, a glass run mounting plate portion 104d that protrudes toward the outside of the vehicle is formed on a frame upper side portion 104c of the window frame 104. The glass run mounting plate portion 104d extends in the front-rear direction.

[0023] (Glass runs for car doors) The glass run 10 is attached to the frame upper edge portion 104c of the window frame 104 from the outer side of the vehicle, and functions as a sealing material for sealing between the window frame 104 and the window glass G, and between the window frame 104 and the vehicle body.

[0024] Specifically, as shown in Fig. 2, the glass run 10 includes a glass run upper edge portion 11, a glass run front vertical edge portion 12, a glass run rear vertical edge portion 13, and a molding 30. The glass run upper edge portion 11, the glass run front vertical edge portion 12, and the glass run rear vertical edge portion 13 are integrated together. The glass run upper edge portion 11 extends in the front-rear direction along the frame upper edge portion 104c of the window frame 104, and is the portion that is attached to the glass run mounting plate portion 104d shown in Fig. 3.

[0025] The glass run front vertical side portion 12 extends downward from a position rearward of the front end portion of the glass run upper side portion 11. The glass run rear vertical side portion 13 extends downward from a position rearward of the glass run upper side portion 11 and forward of the rear end portion of the glass run upper side portion 11. Therefore, the rear end portion of the glass run upper side portion 11 is located rearward of the glass run rear vertical side portion 13.

[0026] As shown in Fig. 3, the glass run upper edge portion 11 is provided with a glass run main body 20 having an insertion groove 14 into which the glass run mounting plate portion 104d is inserted. The glass run main body 20 has an upper plate portion 21 extending along the upper surface of the glass run mounting plate portion 104d, a lower plate portion 22 extending along the lower surface of the glass run mounting plate portion 104d, and an exterior plate portion 23 extending in the vertical direction from the exterior end of the upper plate portion 21 to the exterior end of the lower plate portion 22. The upper plate portion 21, the lower plate portion 22, and the exterior plate portion 23 are integrally molded.

[0027] An insertion groove 14 is formed between the upper plate portion 21 and the lower plate portion 22. The insertion groove 14 opens between the vehicle interior end of the upper plate portion 21 and the vehicle interior end of the lower plate portion 22, and extends in the front-rear direction. The bottom of the insertion groove 14 is formed by the vehicle exterior plate portion 23. The depth of the insertion groove 14 and the dimension in the vehicle interior / exterior direction (left-right dimension) of the glass run mounting plate portion 104d are set so that the vehicle exterior end of the glass run mounting plate portion 104d reaches near the bottom of the insertion groove 14 when the glass run main body 20 is attached to the glass run mounting plate portion 104d.

[0028] The upper plate portion 21, the lower plate portion 22, and the vehicle exterior plate portion 23 are made of a highly rigid material such as a hard resin (e.g., polypropylene mixed with talc or glass fiber). This allows the glass run mounting plate portion 104d to be firmly held by the upper plate portion 21 and the lower plate portion 22.

[0029] An upper engagement protrusion 21a protruding downward is formed on the lower surface of the upper plate portion 21. The lower end of the upper engagement protrusion 21a can be formed so as to come into contact with the upper surface of the glass run attachment plate portion 104d.

[0030] A plurality of lower engagement protrusions 22a protruding upward are formed at intervals in the vehicle interior / exterior direction on the upper surface of the lower plate portion 22. The upper ends of the lower engagement protrusions 22a can be formed so as to contact the lower surface of the glass run mounting plate portion 104d.

[0031] An upper seal lip 24 is provided to protrude upward from the upper portion of the glass run body 20 on the vehicle exterior side, and is deflected toward the vehicle exterior side by contacting the body of the automobile 100. The base end of the upper seal lip 24 is fixed to the vehicle exterior part of the upper surface of the upper plate portion 21 and is integrated therewith.

[0032] An inner seal lip 25 is provided on the upper part of the inner side of the glass run body 20, which bends toward the outer side of the vehicle by contacting the body of the automobile 100. An inner seal portion 26 is provided on the inner end of the upper plate portion 21 so as to protrude downward. The lower end of the inner seal portion 26 is adapted to come into contact with the upper surface of the glass run mounting plate portion 104d.

[0033] A first lower seal portion 27 is provided so as to protrude downward from the lower portion of the glass run body 20 on the outer side of the vehicle. Also, a second lower seal portion 28 is provided so as to protrude downward from the lower portion of the glass run body 20 on the inner side of the vehicle.

[0034] An intermediate seal lip 29 is provided on the lower surface of the lower plate portion 22 between the base end portion of the lower seal portion 27 and the base end portion of the lower seal portion 28. The intermediate seal lip 29 is adapted to come into contact with the upper end of the window glass G in the closed state.

[0035] The upper seal lip 24, the inner seal lip 25, the inner seal portion 26, the first lower seal portion 27, the second lower seal portion 28, and the intermediate seal lip 29 are made of a material that is softer and more easily elastically deformed than the high rigidity material. The upper seal lip 24, the inner seal lip 25, the inner seal portion 26, the lower seal portion 27, the lower seal portion 28, and the intermediate seal lip 29, together with the upper plate portion 21, the lower plate portion 22, and the vehicle exterior plate portion 23, are parts that constitute the glass run main body 20.

[0036] The molding 30 is a member used as part of the design of the vehicle, and is generally made of a hard material such as stainless steel or an aluminum alloy. In this embodiment, it is made of a stainless steel plate. The molding 30 is shaped to extend long in the front-rear direction along the glass run body 20, and the front end of the molding 30 is located near the front end of the frame upper side portion 104c of the window frame 104, and the rear end of the molding 30 is located near the rear end of the frame upper side portion 104c of the window frame 104.

[0037] Upper and lower molding side fitting portions 31, 32 that fit onto the vehicle exterior side of the glass run body 20 are formed on the upper and lower parts of the molding 30 so as to extend in the front-rear direction. The upper molding side fitting portion 31 is bent toward the vehicle interior side and then bent downward, so as to have a shape that opens downward. The lower molding side fitting portion 32 is bent toward the vehicle interior side and then bent upward, so as to have a shape that opens upward. The portion of the molding 30 between the upper molding side fitting portion 31 and the lower molding side fitting portion 32 is made into a design portion 33. This design portion 33 is gently curved toward the vehicle exterior side.

[0038] 4 and 6, a first positioning member 34 is fixed to the rear end of the molding 30 (one end in the vehicle front-rear direction) for positioning the molding 30 with respect to the glass run upper edge portion 11. The first positioning member 34 is a resin part formed so as to cover the rear end face of the molding 30 from behind. The first positioning member 34 in this embodiment may be the same as the positioning member in the conventional example, and is therefore denoted by the same reference numeral as the positioning member in the conventional example.

[0039] That is, the first positioning member 34 has a first cover plate portion 34a, a first fixing plate portion 34b, and a first locking portion 34c, and the first cover plate portion 34a, the first fixing plate portion 34b, and the first locking portion 34c are integrally molded. The first cover plate portion 34a extends in the vertical direction so as to cover the rear end surface of the molding 30. The upper end portion of the first cover plate portion 34a is located at the same height as the upper end portion of the molding 30, and the lower end portion of the first cover plate portion 34a is located at the same height as the lower end portion of the molding 30. That is, the shape and size of the first cover 34a are set so that the rear end surface of the molding 30 is not visible when the molding 30 with the first positioning member 34 fixed is viewed from its rear end portion. The vertical dimension of the first cover plate portion 34a is longer than the dimension in the vehicle interior / exterior direction.

[0040] The first fixing plate portion 34b extends along the vehicle interior surface of the design portion 33 of the molding 30 and is fixed to the molding 30. The upper end of the first fixing plate portion 34b reaches the inside of the upper molding side fitting portion 31. The lower end of the first fixing plate portion 34b reaches the inside of the lower molding side fitting portion 32. The upper and lower ends of the first fixing plate portion 34b are fixed to the upper and lower parts of the molding 30 by crimping so that the first positioning member 34 does not move relative to the molding 30 in any of the front-rear direction, the inside-outside direction, and the up-down direction.

[0041] The first locking portion 34c is integrally formed on the vehicle interior side of the first cover plate portion 34a. The first locking portion 34c is formed in the shape of a protruding piece that protrudes from the first cover plate portion 34a toward the front end portion of the molding 30. The length of the first locking portion 34c in the front-rear direction is set to be shorter than the length of the first fixing plate portion 34b in the front-rear direction. In addition, the first locking portion 34c is spaced from the vehicle interior side of the first fixing plate portion 34b toward the vehicle interior side, and a predetermined gap is formed between the first locking portion 34c and the first fixing plate portion 34b.

[0042] As shown in Fig. 5, on the vehicle exterior side of the glass run main body 20 of the glass run upper edge portion 11, an upper body side fitting portion 23a and a lower body side fitting portion 23b into which the upper molding side fitting portion 31 and the lower molding side fitting portion 32 respectively fit are formed so as to extend in the front-rear direction. That is, as shown in Fig. 3, on the vehicle exterior surface of the vehicle exterior plate portion 23 of the glass run main body 20, a base portion 23c is formed so as to protrude toward the vehicle exterior. This base portion 23c is positioned near the vertical center of the vehicle exterior surface of the vehicle exterior plate portion 23 and is continuous in the front-rear direction.

[0043] The upper body fitting portion 23a is formed of a plate-like portion formed to protrude upward from the protruding tip of the base portion 23c and extend in the front-rear direction. A gap wider than the thickness of the plate material constituting the upper molding fitting portion 31 of the molding 30 is formed between the upper body fitting portion 23a and the vehicle exterior surface of the vehicle exterior plate portion 23.

[0044] The lower body fitting portion 23b is formed of a plate-like portion formed to protrude downward from the protruding tip of the base portion 23c and extend in the front-rear direction. A gap wider than the thickness of the plate material constituting the lower molding fitting portion 32 of the molding 30 is formed between the lower body fitting portion 23b and the vehicle exterior surface of the vehicle exterior plate portion 23.

[0045] The upper body side fitting portion 23a and the lower body side fitting portion 23b extend continuously from the front end to the rear end of the glass run body 20, and are rail-like portions that also function as rails to guide the molding 30 in the forward / backward direction when assembling the molding 30 described later.

[0046] As shown in Fig. 3, the upper molding side fitting portion 31 of the molding 30 is arranged so as to surround the upper body side fitting portion 23a of the glass run body 20 from above, and in this state, the upper molding side fitting portion 31 fits into the upper body side fitting portion 23a. The lower molding side fitting portion 32 of the molding 30 is arranged so as to surround the lower body side fitting portion 23b of the glass run body 20 from below, and in this state, the lower molding side fitting portion 32 fits into the lower body side fitting portion 23b. When the upper molding side fitting portion 31 and the lower molding side fitting portion 32 fit into the upper body side fitting portion 23a and the lower body side fitting portion 23b, respectively, the shapes of the upper molding side fitting portion 31 and the lower molding side fitting portion 32 make it difficult for the molding 30 to displace in the vehicle width direction and the up-down direction relative to the glass run body 20.

[0047] In this embodiment, the upper body side fitting portion 23a and the lower body side fitting portion 23b are integrally molded with the vehicle exterior plate portion 23, so that the upper body side fitting portion 23a and the lower body side fitting portion 23b can also be made of a highly rigid material. Therefore, when the upper molding side fitting portion 31 and the lower molding side fitting portion 32 are fitted into the upper body side fitting portion 23a and the lower body side fitting portion 23b, respectively, the molding 30 is less likely to come off the glass run body 20.

[0048] An upper contact portion 40 made of an elastic material is formed on the vehicle exterior side of the glass run body 20, which contacts the upper part of the vehicle exterior surface of the molding 30. The upper contact portion 40 is provided so as to protrude toward the vehicle exterior from the vehicle exterior surface at the base end of the upper seal lip 24, and the upper contact portion 40 and the upper seal lip 24 are molded as one piece. The lower surface on the tip side of the upper contact portion 40 contacts the molding 30 from above, which eliminates a gap between the upper part of the molding 30 and the upper part of the glass run body 20, improving the external appearance.

[0049] Furthermore, on the vehicle exterior side of the glass run body 20, a lower contact portion 41 made of an elastic material that contacts the lower portion of the vehicle exterior surface of the molding 30 is formed at a portion downwardly spaced from the upper contact portion 40. The lower contact portion 41 contacts the molding 30 from below, thereby eliminating a gap between the lower portion of the molding 30 and the lower portion of the glass run body 20, improving the external appearance.

[0050] In addition, a protrusion 23d that comes into contact with the vehicle inner surface of the molding 30 is provided on the vehicle outer side of the glass run body 20 and protrudes toward the vehicle outer side. The protrusion 23d comes into contact with the vehicle inner surface of the molding 30, thereby making it possible to prevent a wide area of ​​the vehicle outer side plate portion 23 from coming into contact with the molding 30. The protrusion 23d can be molded integrally with the vehicle outer side plate portion 23.

[0051] As shown in Figure 5, the rear portion of the upper edge portion 11 of the glass run (the portion of the upper edge portion 11 of the glass run rearward of the rear vertical side portion 13 of the glass run) has an outer vertical plate portion 45 that is positioned on the outside of the vehicle and extends in the vertical direction, and an inner plate portion 56.

[0052] 7, a first insertion hole 58 is opened at the rear end of the glass run upper side portion 11, into which the first locking portion 34c of the first positioning member 34 fixed to the molding 30 is inserted. The first insertion hole 58 is formed between the outer vertical plate portion 45 and the inner plate portion 56, and the first locking portion 34c inserted into the first insertion hole 58 is accommodated in an accommodation space R1 defined by the outer vertical plate portion 45 and the inner plate portion 56.

[0053] When the first locking portion 34c is locked to the glass run upper edge portion 11, the rear end face (one end face in the vehicle front-rear direction) of the first positioning member 34 and the rear end face (one end face in the vehicle front-rear direction) 56b of the glass run upper edge portion 11 are arranged to be substantially flush with each other. As a result, when the molding 30 is attached to the glass run upper edge portion 11, the positions of the rear end faces are substantially in the same position in the vehicle front-rear direction, which further improves the appearance.

[0054] 8, a second positioning member 35 is fixed to the front end portion (the other end portion in the vehicle front-rear direction) of the molding 30 for positioning the molding 30 with respect to the glass run upper side portion 11. The second positioning member 35 is a resin part formed so as to cover the front end face of the molding 30 from the front.

[0055] The second positioning member 35 has a second cover plate portion 35a, a second fixing plate portion 35b, and a second locking portion 35c, and the second cover plate portion 35a, the second fixing plate portion 35b, and the second locking portion 35c are integrally molded. The second cover plate portion 35a extends in the vertical direction so as to cover the front end surface of the molding 30. The upper end portion of the second cover plate portion 35a is located at the same height as the upper end portion of the molding 30, and the lower end portion of the second cover plate portion 35a is located at the same height as the lower end portion of the molding 30. That is, the shape and size of the second cover 35a are set so that the front end surface of the molding 30 is not visible when the molding 30 with the second positioning member 35 fixed is viewed from its front end portion. The vertical dimension of the second cover plate portion 35a is longer than the dimension in the vehicle interior / exterior direction.

[0056] Two upper claws 35d are formed at an upper portion of the second fixing plate 35b with a gap therebetween in the front-rear direction. Each upper claw 35d has a shape that is long in the front-rear direction. The rear end of the upper claw 35d is integrally formed with the upper portion of the second fixing plate 35b, while the other portion is spaced from the upper portion of the second fixing plate 35b toward the inside of the vehicle. When a force toward the outside of the vehicle acts on the upper claw 35d, the upper claw 35d elastically deforms toward the outside of the vehicle starting from the vicinity of the rear end. The number of upper claws 35d is not limited to two, and may be one, or three or more.

[0057] Two lower claws 35e are formed at a distance in the front-rear direction on the lower portion of the second fixing plate portion 35b. Each lower claw 35e has a shape that is long in the front-rear direction. The rear end of the lower claw 35e is integrally formed with the lower portion of the second fixing plate portion 35b, while the other portion is separated from the lower portion of the second fixing plate portion 35b toward the vehicle interior side. This allows the lower claw 35e to be elastically deformable, similar to the upper claw 35d.

[0058] Two upper notches 31a are formed in the upper molding-side fitting portion 31 of the molding 30 with a gap therebetween in the front-rear direction. The gap between the upper notches 31a is approximately the same as the gap between the upper claw portions 35d. Moreover, two lower notches 32a are formed in the lower molding-side fitting portion 32 of the molding 30 with a gap therebetween in the front-rear direction. The gap between the lower notches 32a is approximately the same as the gap between the lower claw portions 35e.

[0059] When the second positioning member 35 is fixed to the molding 30, the second fixing plate portion 35b is inserted from the front end portion of the molding 30 into the upper molding side fitting portion 31 and the lower molding side fitting portion 32. Then, the upper claw portion 35d is pushed toward the vehicle exterior by the inner surface of the upper molding side fitting portion 31 and elastically deformed, and the lower claw portion 35e is pushed toward the vehicle exterior by the inner surface of the lower molding side fitting portion 32 and elastically deformed, allowing the second fixing plate portion 35b to be inserted. Then, when the upper claw portion 35d reaches a position corresponding to the upper cutout portion 31a, the shape of the upper claw portion 35d is restored and the upper claw portion 35d is disposed in the upper cutout portion 31a and is caught on the edge of the upper cutout portion 31a. Furthermore, when the lower claw portion 35e reaches a position corresponding to the lower cutout portion 32a, the shape of the lower claw portion 35e is restored and disposed within the lower cutout portion 32a, and the lower claw portion 35e is hooked onto the edge of the lower cutout portion 32a. In other words, the upper claw portion 35d and the lower claw portion 35e formed on both vertical sides of the second positioning member 35 are elastically deformed to be hooked onto the upper cutout portion 31a and the lower cutout portion 32a formed on both vertical sides of the molding 30, thereby fixing the second positioning member 35 to the molding 30.

[0060] The second locking portion 35c is integrally formed on the vehicle interior side of the second cover plate portion 35a. The second locking portion 35c is formed in the shape of a protruding piece protruding from the second cover plate portion 35a toward the rear end of the molding 30. The length of the second locking portion 35c in the front-rear direction is set shorter than the length of the second fixing plate portion 35b in the front-rear direction. In addition, the second locking portion 35c is spaced from the vehicle interior side of the second fixing plate portion 35b toward the vehicle interior side, and a predetermined gap is formed between the second locking portion 35c and the second fixing plate portion 35b.

[0061] As shown in FIG. 7B of FIG. 7, the front portion of the glass run upper edge portion 11 (the portion of the glass run upper edge portion 11 forward of the glass run front vertical side portion 12) has an outer vertical plate portion 46 arranged on the outer side of the vehicle and extending in the vertical direction, and an inner plate portion 57. A second insertion hole 59 is opened at the front end portion of the glass run upper edge portion 11, into which the second locking portion 35c of the second positioning member 35 fixed to the molding 30 is inserted. The second insertion hole 59 is formed between the outer vertical plate portion 46 and the inner plate portion 57, and the second locking portion 35c inserted into the second insertion hole 59 is accommodated in the accommodation space R2 defined by the outer vertical plate portion 46 and the inner plate portion 57.

[0062] When the second locking portion 35c is locked to the glass run upper edge portion 11, the front end face (the other end face in the vehicle front-rear direction) of the second positioning member 35 and the front end face (the other end face in the vehicle front-rear direction) 57b of the glass run upper edge portion 11 are arranged to be substantially flush with each other. As a result, when the molding 30 is attached to the glass run upper edge portion 11, the positions of the front end faces are substantially in the same position in the vehicle front-rear direction, which further improves the appearance.

[0063] (Installation instructions for the molding) Next, a method for assembling the molding configured as described above will be described. First, the glass run upper edge portion 11, the glass run front vertical edge portion 12, and the glass run rear vertical edge portion 13 are integrated. For example, the glass run upper edge portion 11, the glass run front vertical edge portion 12, and the glass run rear vertical edge portion 13, which are extrusion molded, are connected by a molded portion. In the extrusion molding process, an upper body side fitting portion 23a and a lower body side fitting portion 23b extending in the front-rear direction are formed on the vehicle exterior side of the glass run upper edge portion 11. This process is a glass run molding process.

[0064] 6, a first positioning member 34 having a first locking portion 34c protruding forward is fixed to the rear end of the molding 30. This is a fixing step for fixing the first positioning member 34 to the molding 30. The fixing step and the glass run molding step may be performed in any order, or may be performed in parallel.

[0065] After the fixing step and the glass run molding step, the molding side fitting portions 31, 32 formed at the front end of the molding 30 to which the first positioning member 34 is fixed are fitted to the rear end portions of the body side fitting portions 23a, 23b, and then the molding 30 is moved forward relative to the glass run upper edge portion 11. At this time, the glass run upper edge portion 11 may be fixed and the molding 30 may be moved forward of the glass run upper edge portion 11, or the molding 30 may be fixed and the glass run upper edge portion 11 may be moved rearward of the molding 30. This step is a moving step.

[0066] 7C, the first locking portion 34c is inserted into the first insertion hole 58 of the glass run upper side portion 11 and locked to the periphery of the first insertion hole 58. This step is the first locking step.

[0067] After the moving step, as shown in FIG. 7D in FIG. 7, the second positioning member 35 having the second locking portion 35c is fixed to the front end portion of the molding 30, and the second locking portion 35c is inserted into the second insertion hole 59 of the glass run upper side portion 11 to be locked to the periphery of the second insertion hole 59. This step is the second locking step.

[0068] (Effects of the embodiment) As described above, according to this embodiment, when the molding 30 is assembled by moving it relatively in the front-rear direction with respect to the glass run upper edge portion 11, the first locking portion 34c of the first positioning member 34 fixed to the molding 30 is inserted into the first insertion hole 58 of the glass run upper edge portion 11, thereby locking onto the periphery of the first insertion hole 58. As a result, the rear end portion of the molding 30 is fixed to the glass run upper edge portion 11 via the first positioning member 34.

[0069] On the other hand, with regard to the front end of the molding 30, when the second positioning member 35 is fixed after the moving process of the molding 30, the second locking portion 35c is inserted into the second insertion hole 59 of the glass run upper side portion 11, so that the second locking portion 35c is locked to the periphery of the second insertion hole 59. As a result, the front end of the molding 30 is fixed to the glass run upper side portion 11 via the second positioning member 35.

[0070] Therefore, without using double-sided tape as in the conventional example, both front-to-rear end portions of the molding 30 can be fixed to the upper edge portion 11 of the glass run using the first positioning member 34 and the second positioning member 35. This eliminates the need for many processes such as applying primer, applying double-sided tape, removing the release paper, and pressing, and also suppresses the molding 30 from lifting up over time or due to the external environment. (Embodiment 2) 10 to 12 show a second embodiment of the present invention, in which the mounting structure of the molding 30 is different from that of the first embodiment. In the following, the same parts as those in the first embodiment are given the same reference numerals and their explanations are omitted, and only the parts different from the first embodiment are explained in detail.

[0071] In the second embodiment, as shown in Fig. 10 and Fig. 11, the vertical dimension H1 of the molding 30 is set to be longer than the vertical dimension of the molding 30 of the first embodiment. In this way, when the vertical dimension H1 of the molding 30 is longer, the vertical dimension H2 of the upper body side fitting portion 23a and the lower body side fitting portion 23b must also be increased. However, if the vertical dimension H2 of the upper body side fitting portion 23a and the lower body side fitting portion 23b is increased, it becomes difficult to deform the glass run body 20 so as to conform to the shape of the window frame 3 when attaching the left front door glass run 10 to the left front door 1, since these are made of a highly rigid material.

[0072] In the second embodiment, in order to increase the vertical dimension H1 of the molding 30 while narrowing the dimension H2 of the upper body side fitting portion 23a and the lower body side fitting portion 23b, a separate resin part 35 is provided on the molding 30. The resin part 35 is a member that constitutes a part of the molding 30, and extends long in the front-rear direction along the main body portion (metal part) of the molding 30. The resin part 35 may be made of a material having lower rigidity than the upper plate portion 21, the lower plate portion 22, and the exterior plate portion 23. An upper bent portion 30a is formed at the upper part of the main body of the molding 30, which bends toward the inside of the vehicle compartment, and a lower bent portion 30b is formed at the lower part of the main body of the molding 30, which bends toward the inside of the vehicle compartment.

[0073] An upper protrusion 35a that fits inside the upper bent portion 30a is formed on the upper part of the resin part 35, and a lower protrusion 35b that fits inside the lower bent portion 30b is formed on the lower part of the resin part 35. The resin part 35 is fixed to the main body of the molding 30 by fitting the upper protrusion 35a and the lower protrusion 35b into the upper bent portion 30a and the lower bent portion 30b.

[0074] Upper and lower molding side fitting portions 35c, 35d that fit on the exterior side of the vehicle cabin of the glass run body 20 are formed to extend in the front-rear direction at the upper and lower parts of the resin part 35 on the interior side of the vehicle cabin. As shown in Fig. 10, the upper molding side fitting portion 35d and the lower molding side fitting portion 35c fit into the upper body side fitting portion 23a and the lower body side fitting portion 23b of the glass run body 20, respectively. The vertical dimensions of the upper molding side fitting portion 35d and the lower molding side fitting portion 35c are set narrower than the vertical dimensions of the upper bent portion 30a and the lower bent portion 30b.

[0075] In the second embodiment, after the resin part 35 is assembled to the main body of the molding 30, the molding 30 can be assembled to the glass run main body 20. At this time, the upper coating 40a and the lower coating 41a of the glass run main body 20 come into contact with the upper and lower parts of the main body of the molding 30, respectively.

[0076] In the case of the second embodiment, the same effects as those of the first embodiment can be achieved.

[0077] The above-described embodiment is merely illustrative in all respects and should not be interpreted as being restrictive. Furthermore, all modifications and changes within the scope of the claims are within the scope of the present invention. For example, the present invention can be applied even when the front and rear directions of the above-described embodiment are reversed. [Industrial Applicability]
