At this time, the locking protrusion 62a of the upper end resin portion 62 enters the inside of the upper end portion of the design portion 32A, and the fall off of the bright molding 60 from the design portion 32A is primarily prevented.

  Next, the bright molding 60 is rotated around the upper end locking portion (upper end resin portion 62) in the clockwise direction in FIG. 2, and the retaining resin portion 63 is locked to the lower end portion of the design portion 32A. At this time, the metal molding body 61 is elastically deformed to allow the resin molding section 64 to enter the back surface (inside the vehicle) of the design section 32A. Once the retaining resin portion 63 enters the back surface of the design portion 32A and the retaining inclined surface 63a faces the rear surface of the design portion 32A, the end portion of the retaining inclined surface 63a on the design portion 32A side is the lower end of the design portion 32A. Therefore, the bright molding 60 is not easily detached. In the locked state of the glitter molding 60, a gap s is formed between the folded portion 61c of the metal molding body 61 and the glass run exposed portion 56, and the resin design lip portion 64b hides the glass run exposed portion 56. .

  In a state where the glitter molding 60 is mounted on the design portion 32A of the first door sash body 30A, the full width WD of the glitter molding 60 is the full width of the design portion of the door sash 20. The full width WD of the bright molding 60 is equal to or greater than the full width WC composed of the design portion of the second door sash body 30B and the glass run exposed portion 56 where the bright molding 60 is not mounted (WD ≧ WC). However, the gap P between the body opening side end of the design portion (bright molding 60) in FIG. 2 and the body opening Y and the design portion in FIG. 4 (design portion 32A of the second door sash body 30A). The gap P between the end on the body opening side and the body opening Y is kept the same.

  In the above embodiment, the bright molding 60 is an additional molding mounted on the design portion 32A of the first door sash body 30A, but the additional molding may be a molding other than the luminous molding. Further, although the molding body 61 of the bright molding 60 is made of metal, the molding body 61 can be made of hard resin.
