Claim:
A glass run adapted to be mounted to an inner part of a mounting frame of a vehicle, said glass run comprising: a main body provided with a base portion, and an interior side wall portion and an exterior side wall portion which extend from the base portion, said main body being substantially U-shaped in cross section and having an opening opposite said base portion; an interior seal lip extending into an inner space of the main body from a distal end of the interior side wall portion so as to extend in a direction away from said opening of the main body; and an exterior seal lip extending into the inner space of the main body from a distal end of the exterior side wall portion, wherein a generally linear sub-lip is provided on the interior side wall portion in a section of the glass run which corresponds to a vertical edge of a door glass and extends generally linearly toward said opening of said main body, the sub-lip being integrally extruded with the interior side wall portion, wherein a first restricting projection is provided on a distal end of the interior seal lip on a back surface of said interior seal lip, said back surface of said interior seal lip generally facing the interior side wall portion and said first restricting projection projects towards the interior side wall portion, wherein a projecting length of the sub-lip is set such that a distal end portion of the sub-lip is first brought into abutment with said back surface of the interior seal lip that is opposite to a glass contact surface thereof between the first restricting projection and a base of the interior seal lip when the door glass is inserted into the inner space of the main body, wherein the sub-lip is brought into contact with the interior seal lip for an entirety of a time the door glass is inserted into the inner space of the main body, and wherein a surface treatment to enhance slidability of the sub-lip with respect to said interior seal lip is applied to the distal end portion of the sub-lip.
