Abstract: A glass run for use in a motor vehicle, which is capable of preventing the increase in a sliding resistance against a door glass which is raised and lowered in the glass run. At least one inclined surface is formed in an inside surface of a side wall of the glass run from the position corresponding to a projecting end of a seal lip which extends obliquely inwardly from an opening-side end of the side wall, to a bottom wall. The inclined surface is defined such that the distance between the inclined surface and the door glass gradually increases toward a bottom-side end of the side wall. The inclined surface enables the projecting end of the seal lip which is pushed by the door glass toward the side wall to move smoothly therealong, thereby preventing the increase in the pressing force of the door glass against the seal lip.
