Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a weather strip used for an automobile with a sashless door and a pillar.

[Prior Art] As shown in FIG. 1 as the above weather strip, the weather strip 1 for the front side roof side in which the terminal type molding material 12 is provided at the end of the extrusion molding material 11 and the extrusion molding material 21 are provided. A rear roof side weather strip 2 provided with a terminal molding material 22 at an end and a center pillar weather strip 3 having a terminal molding material 32 provided at the lower end of an extrusion molding material 31 are also used as molding materials. The one connected at 33 is used (Shokaisho 63-916). The center pillar weather strip 3 is fitted into a retainer 5 provided on the center pillar 4, as shown in FIG.

The retainer 5 has a narrow neck portion 52 and a wide head portion 5 in the center.
3 is provided with a locking portion. As shown in FIG. 4, the center pillar weather strip 3 is also formed with a vertical groove 34 having a cross-sectional shape corresponding thereto, and the locking portion of the retainer 5 is fitted therein.

[Problems to be Solved by the Present Invention] By the way, when assembling the weather strip 3 for the center pillar, the opening 341 of the vertical groove 34 is widened to retain the retainer 5.
The head portion 53 is fitted into the wide bottom portion 342. However, since the upper and lower ends of the vertical grooves formed in the molding materials 33 and 34 are formed in the same width as the vertical groove 34 of the extruded molding material 31, it is difficult to widen the opening 341 at the terminal, and the retainer 5 Struggles to fit his head 53. Then, if the opening 341 is forcibly expanded, a crack will occur.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to easily assemble a weatherstrip for a center pillar having a molding material at both upper and lower ends to a retainer.

[Means for Solving the Problem] In the present invention, as shown in FIG. 3, the present invention provides a weather strip for an automobile, in which upper and lower ends of a vertical groove 34 for fitting the retainer of the weather strip for the center pillar ( In the figure, only one side is shown), and an enlarged opening 343 is formed.

[Operation and Effect] By forming the enlarged opening 343, the retainer 5 (FIG. 2) can be easily fitted even at the end of the vertical groove 34. Further, since both ends of the vertical groove 34 are formed by molding, the enlarged opening 343 can be easily formed at the time of molding. Further, the releasability after molding is also good.

[Example] As shown in FIG. 1, the weather strip includes a weather strip 1 for a front roof side in which a terminal type molding material 12 is provided at one end of an extrusion molding material 11, and an extrusion molding material 21. One of the rear side roof side weather strips 2 provided with one terminal type molding material 22 and the center pillar weather strip 3 having the terminal type molding material 32 provided at one end of the extrusion molding material 31, Molding material 3 at each other end
Please connect at 3.

As shown in FIG. 2, the weather strip 3 for the center pillar is fitted to the retainer 5 provided on the center pillar 4,
Front door glass 6 on each side of the hollow seal
The rear edge of a and the front edge of the rear door glass 6b are pressed.

The retainer 5 has a locking portion having a narrow neck portion 52 and a wide head portion 53 protruding from the center of the base portion 51.

On the other hand, in the weather strip 3 for the center pillar, the vertical grooves 34 shown in FIGS. 2 and 4 are provided in correspondence with the locking portions, from the molding material 33 at the upper end to the end molding material 32 at the lower end (first
(Fig.). This vertical groove 34 has an opening 34.
1 has a narrow width corresponding to the neck portion 52 of the retainer 4,
The bottom portion 342 has a wide width corresponding to the head portion 53, and the locking portion of the retainer 5 and the vertical groove 34 are closely fitted. Further, at the upper and lower ends of the vertical grooves 34 located in the molding materials 33 and 32, enlarged openings 343 having an opening width substantially equal to the width of the bottom portion 342 are formed. This vertical groove 34
The extrusion molding material 3 is formed to have a uniform width in the extrusion direction during extrusion molding, and the molding materials 32 and 33 are formed in a stepped shape including the enlarged opening 343 during molding of the mold.

Therefore, in the weather strip of the present invention, when the portion along the center pillar is fitted to the retainer having the wide head provided on the center pillar by the vertical groove, the head of the retainer is also attached to the terminals above and below the vertical groove. It can be easily inserted, and the workability of assembly is improved. Further, the upper and lower ends of the vertical groove are located in the molding material, and the enlarged opening is formed at the time of molding the mold, without any increase in the number of steps. Further, since the mold release after molding is easy, the manufacturing workability is improved, and defects such as tearing do not occur.
