Claim:
A method of producing a weather strip for an automobile, wherein the weather strip comprises (i) a rubber installation base member which has a plastic insert embedded therein, and which comprises a bottom wall portion and side wall portions extending from end edges of said bottom wall portion, respectively, to form a groove portion which is roughly U-shaped in section, and (ii) a holding lip provided inside said groove portion, said method comprising: integrally extrusion-molding the whole weather strip such that a first side of a lid member is connected to an end portion of a first one of said side wall portions, and such that a second side of said lid member is not connected to an end portion of a second one of said side wall portions, said lid member being longer than an opening of said groove portion; processing said holding lip of the extrusion-molded weather strip by inserting a manufacturing tool in said groove portion through said opening; connecting the second side of said lid member to the end portion of the second side wall portion to cover said opening of said groove portion with said lid member; vulcanizing said weather strip; and removing said lid member from said side wall portions.
