  • Weather strip
    Patent number: 6898916
    Abstract: A elastic member of weatherstrip has a base portion with nearly U-shaped section, lips extending from ends of the base portion. An edge of a door glass is adapted to be accommodated in an accommodating portion provided in the elastic member. Each of the inner wall of the accommodating portion, and the inner walls and the outer walls of the lips is covered with a surface treatment layer having a predetermined film thickness. In contrast, the outer wall of the base portion is not covered. An embossing for obtaining a surface like a pearskin-finished one with a surface irregularity is preliminarily performed on the outer wall of the base portion and the outer wall of each of the lips, so that the surface has gloss and color close to those of the surface treatment layer.
