Abstract
A weather strip for a vehicle has a channel-shaped base portion having a U-shaped cross section and provided with retaining lips for retaining a flange of a vehicle body, a seal portion integrally projecting from an outer surface of the base portion, and a core member made of synthetic resin and having a U-shaped cross section, which is embedded in the channel-shaped base portion. The method for producing such a weather strip as described above includes the steps of extruding a strip-shaped thermoplastic synthetic resin sheet having stress concentrating portions which are broken when bending stress is applied thereto, with rubber material to obtain an extruded body, heating the obtained extruded body for curing the rubber material thereof, applying bending stress to the cured extruded body for separating the core member in the stress concentrating portion and bending the separated core member with the rubber material to have a U-shaped cross section.
