In the door trim 1, a fiberboard or the like is molded into a required shape, and a cushioning property is provided on the surface side of a core material 2 having an appropriate shape retention property. It is constituted by covering a skin material 4 such as a vinyl chloride sheet with a pad material 3 such as a polyurethane foam provided therebetween.

Then, an inner seal 7 that is in sliding contact with the window glass 6 is attached to the waist flange portion 5 of the door trim 1. In this conventional example, a resin inner seal bracket 8 is used as the waist flange portion 5 for the core member 2. The inner seal 7 is attached to the flange of the inner seal bracket 8 with a metal stitcher M or the like.

Further, as shown in FIG. 5, there is a conventional example in which the waist flange portion 5 is formed of the core material 2 when the core material 2 is molded and the inner seal bracket 8 is eliminated.

Then, in order to attach the door trim 1 with the inner seal 7 attached thereto to the door inner panel 9, the waist flange portion 5 of the door trim 1 is attached to the door inner panel 9.
The door trim 1 is mounted on the door inner panel 9 by press-fitting and fixing a clip (not shown) mounted on the back surface of the door trim 1 into the mounting hole of the door inner panel 9 so that the door trim 1 is mounted.

At this time, the distance between the door inner panel 9 and the waist flange portion 5 (indicated by symbol A in FIG. 4) is 2 mm to 3 mm.
It is set to 0 mm (abutting state) to some extent or part.

<Problems to be Solved by the Invention> As described above, in the configuration of the conventional automobile door trim 1, when the door trim 1 is attached to the door inner panel 9, the dimension A is set to 0 mm or very small. Since the lower end of the waist flange portion 5, that is, the lower end 8a of the inner seal bracket 8 in the conventional example of FIG. 4 and the lower end edge 2a of the core material 2 in the conventional example of FIG. It is very difficult to install and the workability in the installation work is extremely poor.

In particular, when a wood-based core material is used as the core material 2 of the door trim 1, when it is applied to the conventional example of FIG.
As shown in the figure, the lower end 2a of the core material 2 is damaged,
As shown in FIG. 7, the upper edge 9a of the door inner panel 9 enters between the door trim 1 side and the inner seal 7,
It has been pointed out that the metal stitcher M and other attachments are destroyed and the inner seal 7 is not attached properly.

The present invention has been made in view of the above circumstances, and an object of the present invention is to significantly improve the mounting workability when mounting the door trim on the door inner panel, and to prevent damage to the door trim and the inner seal. An object of the present invention is to provide an automobile door trim that does not hinder the installation.

When attaching the door inner panel to the door inner panel, the guide piece comes into contact with the upper edge of the door inner panel and moves along the guide piece. Door trim Te is characterized in that it is guided to a predetermined position.

<Operation> As is apparent from the above configuration, the lower end of the waist flange and the lower end of the inner seal are in close contact with each other, and further, the emboss formed on the inner seal bracket has the lower end of the passenger compartment. Since the guide piece that inclines inward is integrally formed, when the door trim is attached to the door inner panel, the guide piece comes into contact with the upper edge of the door inner panel, and the door trim is guided along the guide piece. The door trim is securely installed in place.

Therefore, it is possible to reliably prevent the upper edge of the door inner panel from biting into the core material of the door trim and the door inner panel from entering between the door trim and the inner seal.

<Embodiment> Hereinafter, a vehicle door trim according to the present invention will be described in detail with reference to the accompanying drawings.
