Abstract
A front door weather strip is annular as a whole, and has one mold molding section fixed to the corner section which is the rear side upper section of a door frame, and one extrusion molding section. The extrusion molding section includes a base section and a hollow sealing section. A seal lip is integral with the part of the extrusion molding section which corresponds to the upper section of the door frame. The length of the seal lip is gradually changed at a front upper corner part. During extrusion molding, the part of the extrusion molding section which corresponds to a front lower corner part is formed as follows: That is, the sealing section is larger in height than the other part. At least the part of the extrusion molding section which corresponds to the lower section is smaller in wall thickness of the vehicle outside base end part of the sealing section than the part which corresponds to the upper section.
