Patent ID: 7513079

Claim:
A method for manufacturing a glass run having an extruded portion formed by extrusion and a molded portion molded by molding so as to be continuously joined to the extruded portion, wherein the glass run includes: a main body portion, which is adapted to be mounted in a sash provided on a body or door in a vehicle, including substantially a U-shaped cross section provided with a base portion and interior and exterior side wall portions extending from opposite ends of the base portion; a pair of seal lips extending from distal ends of the interior and exterior side wall portions toward an inside of the main body portion so as to perform a sealing of a door window glass; and an extension portion formed in the base portion so as to extend and contract in a direction traversing the interior and exterior of the vehicle, wherein the extension portion is located at a position deviated from a center of the base portion in a vertical side portion of the body or the door, and the extension portion is located at a position of the base portion to which an end face of the door window glass is opposed in an upper side portion of the body or the door, the method comprising: an extruding step for forming an extruded portion by extrusion while maintaining a state in which the extension portion is contracted in the direction traversing the interior and exterior of the vehicle; a cutting step for cutting the extruded portion so formed to a predetermined length; and a molding step for setting an end portion of the extruded portion that has been so cut in a mold in such a state that the extension portion is made to extend by partially releasing the maintained contracted state of the extension portion at the end portion of the extruded portion, and connecting molding a molded portion having the same cross section as that of the end portion of the extruded portion while including an extension portion therein such that the extension portion in the vertical side portion and the extension portion in the upper side portion are continuous through the extension portion in the molded portion.
