(57) [Summary] [Purpose] In a weather strip mounted on the opening edge of a door of a body panel, a difference in surface pressure of a seal portion between an extrusion molding portion of the weather strip and a molding portion connected thereto is determined. To prevent water leakage due to insufficient sealing pressure when the door is closed. In a weather strip 1 of an automobile mounted on an edge of a door opening of a body panel, a mold forming portion 3 connected to a lower end of an extrusion forming portion 2 of the weather strip 1 has a chamber in cross section at its seal portion 6. A hollow portion 6a continuous in the longitudinal direction is formed in approximately half of the outer side, and a plurality of lightening portions 7 are intermittently formed in the longitudinal direction in approximately half of the indoor side, and the lightening portion 7 and the hollow are formed. An intermediate bridge 8 is formed between it and the portion 6a.

い。2. Description of the Related Art As shown in FIG. 6, a weather strip 1 is attached to an opening edge portion of a door of a body panel of a hard top vehicle, and a lower end portion (arrow A) of a rising portion 1a on the rear side of the weather strip 1 is attached. An enlarged view of the front surface side is shown in FIG. 7, and an enlarged view of the back surface side of the lower end portion is shown in FIG. The lower end of the rising portion 1a connects the molding portion 3 to the lower end of the extrusion molding portion 2, and the cross section of the extrusion molding portion 2 taken along the line B'-B 'is as shown in FIG. An intermediate bridge 11 is provided in the hollow portion 10 a of the valve 10.
On the other hand, the mold part 3 has the structure shown in FIG.
As shown in FIG. 11 (D'-D 'cross-section) and in order to prevent gas scratches on the surface due to an increase in the wall thickness of the die-molding portion and to facilitate workability during die-molding. In the hollow portion 12a of the seal portion 12, an intermediate bridge cannot be provided unlike the seal portion 10 of the extrusion molding portion 2.

The sealing pressure of the mold forming part 3 having a small value was small, which caused water leakage. As a countermeasure,
Conventionally, the pad 13 is inserted into the hollow portion 12a of the seal portion 12 from the center core removal hole 14 to increase the rigidity of the mounting seal portion 12 and eliminate the difference in rigidity between the extrusion molding portion 2 and the seal portion 10. I was trying to prevent water leakage.

It was Therefore, in view of such conventional problems, the present invention is configured by eliminating the difference in rigidity between the die-molded portion and the extruded-molded portion without inserting a pad into the hollow portion of the die-formed portion. It is an object of the present invention to provide a weather strip for an automobile, in which the cost and the cost are reduced.
