    • 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.
    • 前门防风条整体呈环状,并且具有固定在作为门框的后侧上部的角部的一个模具成型部和一个挤出成型部。 挤出成形部包括基部和中空密封部。 密封唇与挤压成型部分对应于门框的上部的部分是一体的。 密封唇的长度在前上角部逐渐变化。 在挤出成形时,对应于前下角部的挤压成形部的部分形成如下:即,密封部的高度比其他部分大。 挤压成形部的与下部对应的部分的至少一部分比密封部的车辆外侧基端部的壁厚小于与上部对应的部分的壁厚。
