DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a weather strip mounting structure according to the present invention. The center pillar 1 has a mountain-shaped cross section in which the front side and the rear side are inclined as described above. ing. In the illustrated example, the left side is the front side, and the right side is the rear side. A retainer 2 formed by bending a band-shaped metal plate is welded to the front side surface 1a of the center pillar 1, and a clip hole 3 is formed through the rear side surface 1b. The clip hole 3 is located near a rear side edge of the center pillar 1.

The front end of the retainer 2 is bent inward in a U-shaped cross section, thereby forming a fitting portion 4. An end of the center pillar 1 on the center side rises to the outside of the vehicle along the center line of the center pillar 1, and its tip is bent toward the rear side as a locking portion 5. The locking portion 5 extends substantially parallel to the rear side surface 1 b of the center pillar 1.

The weather strip 6 attached to the center pillar 1 includes a first hollow seal portion 7 covering the front side surface 1a of the center pillar 1 and a rear side surface 1b.
And a second hollow seal portion 8 covering the center pillar 1 and both are integrally and continuously formed at the center of the center pillar 1. The upper end of the weather strip 6 is continuous with the door weather strip along the side edge of the vehicle body roof.

The first hollow seal portion 7 has a relatively thick base portion 9, and a seal portion 10 bulging in a substantially arc-shaped cross section is formed outside the base portion 9 so as to cross the inside of the hollow portion. Are formed with struts 11,12. Further, a seal lip 13 is formed on a side edge of the seal portion 10 to seal a gap between the side edge of the center pillar 1 and a welt (not shown). An end of the base 9 on the front side is extended as a projection 14.
Are fitted to the fitting portion 4 of the retainer 2.
The first hollow seal part 7 is entirely formed of sponge rubber.

On the other hand, the second hollow seal portion 8 has a base portion 15 formed of hard solid rubber, and a seal portion 16 bulging in a substantially arc-shaped cross-section outside the base portion 15 formed of sponge rubber. I have. The seal 16 has a rear end supported by a solid rubber support 17 that branches off from the base 15 and includes sponge rubber supports 18 and 19 in the hollow space. Reference numeral 20 denotes a seal lip for sealing between the seal lip 13 and a welt (not shown) on the side edge of the center pillar 1. The base 15 made of solid rubber is used for the weather strip 6.
At the center in the width direction, that is, the connecting portion with the first hollow seal portion 7, and is curved in a substantially U-shape toward the front side. Thus, an engagement groove 21 that can be engaged with the locking portion 5 of the retainer 2 is formed. And the base 1
5 has a rear end portion made of a synthetic resin clip 22.
The center pillar 1 is fixed to the clip hole 3. Reference numeral 23 denotes a front door glass, and 24 denotes a rear door glass.

The procedure for mounting the weather strip 6 having the above structure is as follows. First, the center engaging groove 21 is engaged with the engaging portion 5 at one end of the retainer 2 and the first hollow seal portion 7 is engaged.
Is fitted into the fitting portion 4 at the other end of the retainer 2 to hold the base 9 of the first hollow seal portion 7 in the retainer 2. In this state, the entire weather strip 6 is temporarily fixed to the center pillar 1. Then, the base portion 15 of the second hollow seal portion 7 is directly fixed to the center pillar 1 by press-fitting the clip 22. This allows
The weather strip 6 is firmly attached to the center pillar 1.

Therefore, according to the above configuration, the first hollow seal portion 7 side and the second hollow seal portion 8 side can be sequentially and reliably assembled to the center pillar 1, and the wide weather strip 6 can be easily formed. Can be attached.
In particular, the second hollow seal portion 8 side has a plurality of clips 2
2, the work is extremely simple.

Further, since the retainer 2 is provided only on the side surface 1a on the front side of the center pillar 1, the retainer 2 can be reduced in size and weight, and the number of processing steps can be greatly reduced. In the rear side surface 1b of the center pillar 1, only the processing of the clip hole 3 is sufficient, so that the overall processing cost is greatly reduced.

In the above embodiment, the side where the retainer 2 is provided is the front side, but it is of course possible to reverse the configuration.

[0018]

As is apparent from the above description, according to the weather strip mounting structure of the center pillar according to the present invention, only the first hollow seal portion is held via the retainer, and the second hollow seal portion is clipped. Since it is directly fixed to the center pillar at, a wide weather strip can be easily attached, and the workability is improved.
