DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. The drawings show a case where the present invention is applied to an automobile front door as shown in FIG. 4, wherein FIG. 1 is a sectional view thereof, and FIG. 2 is an exploded sectional view before assembly. Is a door trim main body, 2 is a weather strip for window glass sealing mounted on a garnish portion of the door trim main body 1, 3 is a door panel, and 4 is a window glass.

[0007] The weatherstrip 2 includes an extension portion 21 which is formed on both legs of a holding frame main body 21 having a substantially U-shaped cross section having an open lower end and rising along the outer surface thereof.
a, 21b, an inward molding part 2 covering the upper end of the garnish at the upper end of the outer extension 21a.
4 and a core member in which an inclined guide piece 25b whose tip is bent to a downward contact piece 25c is connected to an extension end of an inner extension 21b via an outward piece 25a. The lip portion 22 made of an elastic material such as a soft vinyl chloride resin is stretched integrally from the outer surface of the above-mentioned outer extension portion by the above-mentioned means. In this case, a seal piece 27 made of an elastic material for holding the sealing material and a protective film that covers the surface of the leg of the holding frame body 21 from the upper surface of the molding 24 are integrally provided. On the other hand, as the garnish portion, a flange having a flange 11 suspended from the tip of the garnish portion is used, and the downward contact piece 25c of the cored bar member is brought into contact with the flange 11 of the garnish portion to resiliently lock. With the holding frame body 2
1, the insertion end of the door panel 3 is inserted, whereby the weather strip 2 is positioned and fixed under the seal by the seal piece 27.

The flange 11 can be formed in the longitudinal direction over the entire garnish portion. However, as shown in FIG. 2, a plurality of the flanges 11 can be formed intermittently in the longitudinal direction of the garnish portion. Is preferable because it can improve the molding efficiency and reduce the weight. The flange 11 may be formed integrally with the door trim main body 1 made of a synthetic resin such as polypropylene as shown in FIG. 3 at the same time as the injection molding, as shown in FIGS. It is also possible to create a separate component such as this and attach it integrally to the door trim main body 1 with screws or the like.

The flange 11 is provided on the door panel 3.
The door trim 3 is formed on the inner side of the door panel 3 so that the door trim main body 1 can be attached to the door panel 3 only from the horizontal direction. That is, conventionally, when the door trim body 1 is attached to the door panel 3, the door trim body 1 is once raised to a position higher than the door panel 3 and then pushed horizontally to be hooked. Since the door trim 11 is formed inside the door panel 3, it is not necessary to lift the door trim main body 1, and the assembling work can be performed simply and accurately.

In this construction, the weather strip 2 has extending portions 21a and 21b extending along the outer surfaces of both legs of a holding frame main body 21 having a substantially U-shaped cross section and an open lower end. At the end of the outer extension 21a, an inward molding portion 24 is formed to cover the top surface of the tip of the garnish portion, and the tip of the inner extension 21b is bent to a downward contact piece 25c via an outward piece 25a. While a lip portion 22 made of an elastic material is integrally provided on the outer extension portion 21a of the core metal member having the formed inclined guide piece 25b connected thereto, the garnish portion has a flange 11 hanging at the tip. First, the weather strip 2 is inserted into the insertion end of the door panel 3 so that the lower end of the holding frame main body 21 has an opening so that the holding strip main body 21 can be inserted. Insert the end, followed by a molding portion 24 of the weather strip 2 inclined guide piece 25
When the front end of the garnish portion of the door trim main body 1 is pushed into the gap between the garnish portion and the flange 11, the core member of the weather strip 2 made of a metal plate is resilient. While the tip is guided by the inclined guide piece 25b, the outward piece 25a is pushed down to widen the gap between the molding portion 24 and the inclined guide piece 25b, and the outward piece 25a at the time when the tip of the flange 11 exceeds the downward contact piece 25c. Returns to the old state, and the outer extension 2
Inward molding 24 formed at the extension end of 1a
Covers the upper surface of the tip of the garnish part and the flange 1
1 abuts against the downward contact piece 25c and is elastically locked,
The weather strip 2 is positioned and fixed. Therefore, the mounting position of the weather strip 2 can be accurately assembled by a simple assembling operation without displacement, and a stable sealing performance can be obtained. In addition, the presence of the molding portion 24 can prevent sound leakage and wind leakage without generating a gap between the molding and the door trim, and also provide an excellent appearance. Furthermore,
Since there is no need to move the door trim main body 1 in two directions, that is, the vertical direction and the horizontal direction as in the related art during the assembling work, the work efficiency can be greatly improved.
