Claim:
An end cap which is attached to an end portion of a molding main body having an opening in its cross section and which is attached to a vehicle body together with the molding main body through an operation of pressing a clip, which projects from the opening of the molding main body, via the molding main body to thereby lock the clip to the vehicle body, the end cap comprising: a cap portion which covers the end portion of the molding main body when the end cap is attached to the molding main body; an insertion portion whose proximal end portion is continuous with an inner surface of the cap portion and which is inserted into the molding main body such that a forward end portion of the insertion portion is first inserted into the molding main body; and a rib which is provided on the insertion portion such that the rib projects from the opening of the molding main body and which receives a reaction force from the vehicle body when a forward end portion of the rib butts against the vehicle body due to a pressing force which is applied to the clip via the molding main body so as to lock the clip, wherein the insertion portion includes a vertical plate portion having an insertion sliding-contact surface which comes into sliding contact with a guide surface of the molding main body when the insertion portion is inserted into the molding main body, and a horizontal plate portion with which a proximal end portion of the rib is continuous, wherein the vertical plate portion is provided such that its one edge portion butts against an inner surface of a wall portion of the molding main body located on the side opposite the opening so as to receive the pressing force which is applied to the clip via the molding main body so as to lock the clip, and the rib is located on the outboard side of an imaginary plane containing the vertical plate portion.
