2. Description of the Related Art As a weather strip attached to the above-mentioned opening edge, one having a mounting base having a U-shaped cross section which is assembled to a flange formed along the opening edge is generally used.

When the edge of an interior material such as a ceiling material or a garnish that covers the side surface of the passenger compartment is abutted against the side surface of the vehicle base side of the mounting base of the weather strip, the weather strip and the interior material Due to mounting variations, a gap is likely to occur at the abutting part.

Therefore, as a countermeasure against this gap, a lip projecting in the vehicle interior direction from a position higher than the abutting portion is provided on the side wall of the mounting base on the vehicle interior side, and the abutting portion is covered from above with this lip. Means for concealing (Actual exploitation 57-108483
No.), a side wall of the mounting base on the vehicle interior side has a side surface portion substantially parallel to the side wall and forms a rectangular or oval hollow portion with the side wall, and an end of the interior material is formed on the side surface of the hollow portion. A means for pressing the edges (Shokai 57-159813) is used.

However, in the former method, the abutting portion is covered with a lip at its upper portion, but the lip is not in close contact with the edge of the interior material, and a gap is formed between the two, or the interior material is attached to the weather strip. Depending on the direction, the lip may be caught between the side surface of the mounting base and the edge of the interior material.

In the latter means, the workability of assembling is not good because the edge of the interior material is caught in the hollow portion depending on the direction in which the edge of the interior material is attached to the hollow portion. In addition, the hollow portion is deformed so that it looks bad.

Edge 51 of roof side garnish 5C
Is assembled to the contact surface 461 of the lip portion 460 that is inclined outward from the center of the passenger compartment. In this case as well, like the garnish 5A shown in FIGS. 2 and 3,
The edge 51 of the roof side garnish 5C is assembled to the contact surface 461 smoothly and with good adhesion.

FIG. 6 shows another embodiment of the weather strip attached to the opening edge of the back door opening.

The difference between this weather strip 4C and the above weather strip 4A is that the tip of the lip portion 470, which is provided on the side wall 411 of the mounting base 41 on the vehicle interior side and has an inclined contact surface 471, has a side wall. Although it extends to the tip of 411, it is a free end without being joined to the side wall 411, and the root portion 472 side of the abutting portion 47 covers the entire inner surface from the side wall 411 to the bottom surface of the sponge rubber material. Covering.

Since the tip of the lip portion 470 is a free end, the followability of the lip portion 470 when the inclined contact surface 471 is pushed by the edge of the interior material is good. Further, the entire surface of the mounting base portion 41 on the indoor side is made of a sponge rubber surface, which has a good appearance.

FIG. 7 shows still another embodiment of the weather strip attached to the opening edge of the back door opening.

The difference between this weather strip 4D and the above weather strip 4A is that the length of the lip portion 480 is shortened.

In the abutting portion 48 provided with the lip portion 480 having the contact surface 481, the length of the lip portion 480 is made substantially the same as the protruding length of the root portion 482, and the solid rubber material 410 is extended to the inner surface of the lip portion 480. is there.

The end edge 51 of the garnish 5D is bent from the main body portion into an L shape, and its length is almost the same as the length of the lip portion 480. Then, the end edge 51 is assembled by pressing the curved contact surface 481 of the lip portion 480 of the abutting portion 48 and sandwiching the lip portion 480 with the root portion 482. By extending the solid rubber material inside the lip portion 480, it is possible to reduce the variation in the shape at the time of molding and to shorten the length of the lip portion 480. In addition, in each of the above-described examples, if a notch is provided inside the inversion part between the root part and the lip part, the lip part is more easily bent, and the abutting with the edge of the interior material is easier. And it becomes certain.

[0027]

As described above, according to the present invention, an abutment having a rigid root portion and a lip portion having an inclined or curved contact surface on the side wall of the weather strip mounting base portion on the vehicle interior side. Since the interior material edge is abutted against the inclined or curved contact surface of the lip portion of the abutment portion, even if the assembly direction of the interior material edge to the weather strip changes, The edge of the interior material can be brought into close contact with the abutting portion with good workability.
