[Figure 5] The cross-sectional end view is taken along line CC in FIG. 4(c). DETAILED DESCRIPTION OF THE INVENTION

[0008] An example of a sash molding mounting structure according to the present invention will be described below with reference to the drawings, but the present invention is not limited to this.

[0009] FIG. 1( a ) shows an example of a front door having a door glass 2 that can be raised and lowered at the top of a door panel 1 , and a door sash 3 for holding the edge of the door glass 2 . An enlarged view of the upper edge portion 4 constituting the door sash 3, that is, the open end side of the door panel 1, i.e., the rear terminal side 5 of the front door, is shown in Figure 1(b), and a cross-sectional end view of the same taken along line AA is shown in Figure 1(c). The upper edge portion 4 is made up of a metal upper sash 6 extending in the longitudinal direction of the vehicle along the upper edge portion of the door glass 2, a glass run 10 made of a rubber material provided along the upper sash 6, and a sash molding 30 attached to the glass run 10. In this embodiment, an end portion 7 having a substantially U-shaped cross section is formed on the rear end surface of the upper sash 6 as shown in FIG. 2(b).

[0010] As shown in Figure 1(c), the glass run 10 has, integrally, attachment portions 11 and 12 for attaching to the upper sash 6 on the inside of the vehicle, a sealing portion (channel portion) 13 for sealing between the upper sash 6 and the door glass 2 on the underside of the vehicle, and an attachment portion 14 for attaching the sash molding 30 on the outside of the vehicle. The structures of the assembly portion and the sealing portion are not limited to those in this embodiment. The mounting portion 14 has a molding facing portion 15 that faces the sash molding 30, ribs 16a and 16b extending from the upper and lower ends thereof toward the molding facing portion, respectively, and a guide portion 17 with a T-shaped cross section that protrudes from the molding facing portion 15 toward the outside of the vehicle. FIG. 2(b) shows the rear end side of the mounting portion 14 extending in the vehicle front-rear direction along the upper sash 6. A latched piece 19 and an insertion portion 20 are formed at a predetermined distance from the rear end of the mounting portion 14, and a guide portion 17 extends from the insertion portion 20 toward the front of the vehicle. The engaging piece 19 is a small protruding piece with a width in the front-to-rear direction of the vehicle that protrudes from the molding opposing portion 15 toward the outside of the vehicle, and may have a T-shaped cross section as in this embodiment, or an L-shaped cross section as shown in Figure 4(b), and there are no restrictions on its cross-sectional shape. The insertion portion 20 may be formed by cutting out a part of the guide portion 17 . A rear end surface 15a of the molding facing portion 15 is disposed on the vehicle front side of the terminal portion 7 of the upper sash, and a fitting hole 21 that opens on the vehicle rear side is formed between the rear end surface 15a and the terminal portion 7.

[0011] In contrast, the sash molding 30 includes a molding body 31 extending in the longitudinal direction of the vehicle along the molding-facing portion 15 of the glass run, and a resin terminal member 40 attached to the end of the molding body 31. As shown in Figure 1(c), the molding main body 31 has a design portion 32 that forms the design surface on the exterior side of the vehicle, flange portions 33a and 33b that are formed by folding the upper and lower ends of the design portion 32 back toward the interior side of the vehicle, and a resin material 34 on the interior side of the vehicle, and a retaining portion 35 with a roughly C-shaped cross section is formed in approximately the center of the resin material 34. In this embodiment, both edges of the design portion 32 made of SUS material or the like are folded back toward the inside of the vehicle to form flange portions 33a, 33b, and a resin material 34 is integrally molded on the inside of this design portion and flange portion by composite extrusion molding or the like. FIG. 2(a) shows an example of the structure of the terminal side of the sash molding 30. The terminal member 40 has a cover portion 41 facing the rear end portion of the molding body 31, and a base portion 42 extending from the cover portion 41 along the design portion 32 of the molding body 31 and engaging with the flange portions 33a, 33b. The cover portion 41 has a fitting claw 43 protruding from the front surface thereof toward the front of the vehicle. As shown in FIG. 3, the fitting claw 43 has a head 43a at its tip end, and the head 43a is capable of bending toward the outside of the vehicle when pressed from the inside of the vehicle. In addition, in this embodiment, an opening 45 is formed in approximately the center of the base portion 42, and a locking portion 46 is formed on the front side of the opening 45, and the opening 45 is an approximately rectangular opening in the base portion 42, and the locking portion 46 protrudes from the base portion 42 at an angle toward the inside of the vehicle. By attaching the terminal member 40 to the molding body 31, the rear end of the molding body 31 is protected by the cover portion 41, and the base portion 42 of the terminal member and the resin material 34 of the molding body are adjacent in the front-to-rear direction of the vehicle.

[0012] The process of attaching the sash molding 30 to the mounting portion 14 of the glass run 10 will be described. As shown in Figure 2(b), with the design surface 32 of the sash molding facing outward, the rear end of the guide portion 17 of the glass run is inserted into the front end of the retaining portion 35 on the inside of the vehicle, and while being guided by the guide portion 17, the sash molding 30 is inserted toward the front of the vehicle so that it fits within the upper and lower insides of the ribs 16a and 16b of the glass run. At this time, the holding portion 35 having a substantially C-shaped cross section embraces the head of the guide portion 17 having a T-shaped cross section, so that the molding body 31 is inserted toward the outside of the vehicle without coming off. The terminal member 40 of the sash molding has a locking portion 46 provided on its base portion 42 inserted into the insertion portion 20 of the glass run from outside the vehicle, and the engaging claw 43 provided on the lid portion 41 is engaged with the engaging hole 21 from the rear side of the vehicle, and its head 43a is engaged with the terminal portion 7. As a result, the sash molding 30 is attached to the glass run 10 as shown in FIG. 2(c), and a cross-sectional end view of the sash molding 30 taken along line BB is shown in FIG. In the attached state, the locked piece 19 of the glass run is disposed within the opening 45 of the terminal member, and further, the locking portion 46 of the terminal member is disposed within the insertion portion 20 of the glass run. At this time, the locked piece 19 and the locking portion 46 are adjacent to each other so that they can come into contact with each other in the longitudinal direction of the vehicle when the glass run is thermally stretched. If the engaging claw 43 is simply engaged with the receiving hole 21, there is a possibility that the engaging claw 43 may come off toward the rear of the vehicle when the door is opened or closed, but by having the receiving piece 19 and the receiving portion 46 engage in the fore-and-aft direction of the vehicle when the glass run is thermally stretched in this way, opening of the terminal member 40 toward the rear of the vehicle can be suppressed and displacement of the sash molding can also be prevented. The opening 45 of the terminal member may be a groove provided in the base portion 42 as long as the engaged piece 19 of the glass run does not come into contact with the base portion 42 or the like other than the engaging portion 46.

[0013] 4 and 5 show Example 2. The terminal member 40 in this embodiment has an opening 47 on the front side of the vehicle at its base portion 42, and a linear portion 48 protrudes from the base portion 42 across the opening 47 in the fore-and-aft direction of the vehicle, and an approximately triangular locking portion 49 is formed approximately in the center of this linear portion 48. When attaching, the engaging piece 19 of the glass run is inserted into the opening 47 of the terminal member, while the engaging portion 49 of the terminal member is inserted into the insertion portion 20 of the glass run. In the attached state, similarly to the first embodiment, the locked piece 19 and the locking portion 49 can come into contact with each other in the longitudinal direction of the vehicle when the glass run is thermally elongated.
