Patent ID: 8869456

Claim:
A glass run of an automobile door, for guiding a door glass in a frame having a substantially U-shaped cross section, the glass run comprising: a body having a substantially U-shaped cross-section including an inner-cabin side wall, an outer-cabin side wall and a connecting wall which connects the side walls and forms a channel; an inner lip which extends toward a connecting wall side from an outer-cabin side surface of said inner-cabin side wall and is slidably brought into contact with said door glass; and an outer lip which extends toward an inner-cabin side from an inner side surface of an end position of said outer-cabin side wall and is slidably brought into contact with said door glass, the outer lip being forked into: an inner-attaching lip which extends toward said connecting wall side from an inner-cabin side surface of the end position of said outer-cabin side wall and which faces said inner lip; and an outer-attaching lip which is substantially perpendicular to a direction in which the inner-attaching lip extends from a base root of the inner-attaching lip and which extends toward an opposite direction from said connecting wall side; wherein: said inner lip substantially has an S shaped cross section, wherein a first portion between a base root of said inner lip and an intermediate part of said inner lip has a convex shape toward said inner-cabin side wall side and a second portion between the intermediate part and a top end of said inner lip has a convex shape toward said outer-cabin side wall side; an inflection point of the S shaped inner lip, on which a direction of a curve of said inner lip changes, is closer to said connecting wall than a top end of the outer-attaching lip of said outer lip; and the base root of the inner lip has a connecting wall side surface which is closer to the connecting wall than the top end of the outer-attaching lip.
