In the type shown in FIG. 8, the bottom surface of the pull handle 3 is fixedly fastened to a mounting base 1a provided on the door trim 1 with screws 6b, and attached to the door inner panel 4 via screws 6a. The mounting bracket 5 is set so as to surround the outer peripheral wall surface of the pull handle 3, and holds the pull handle 3 with the mounting bracket 5 against a load in the direction of the arrow in FIG.

A nonwoven fabric 7 is attached to the outer surface of the pull handle 3 in order to prevent low-pitched sound generated between the inner surface of the bracket 5 and the pull handle 3.

[0007]

However, in such a conventional pull handle 3 mounting structure, a mounting bracket 5 for screwing the pull handle 3 or a mounting bracket for holding the outer peripheral wall surface of the pull handle 3 is provided. It is necessary to fix the bracket 5 to the door inner panel 4 with screws in advance, and the number of parts and the number of mounting steps are increased, resulting in a significant cost increase. In particular, in the case of the type shown in FIG. For example, the non-woven fabric 7 is separately attached to the surface of the mounting bracket 5 facing the mounting bracket 3, thereby increasing the processing cost.

The present invention has been made in view of such circumstances, and even if the mounting bracket provided on the door inner panel side is abolished, sufficient mounting strength can be ensured and the mounting operation is simplified. It is an object of the present invention to provide a mounting structure of a pull handle for a door trim that can be realized.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an armrest by forming a substantially central portion of a door trim so as to protrude into a vehicle interior and mounting a pull handle inside the armrest. In the door trim pull handle mounting structure, the bottom surface of the pull handle is screwed and fixed to a mounting pedestal provided on the inner surface of the armrest of the door trim toward the rear side, and the inner side wall portion of the pull handle is attached to the door trim. It is characterized by being fixed to the inner panel.

Here, the door trim may be of a laminated structure in which a skin material is coated and adhered to the surface of a resin core material, or may be a single-piece synthetic resin molded article.

The pull handle is made of a synthetic resin injection-molded body, and is a case-shaped one having a flange set on the periphery of an opening provided on the upper surface. In addition to the mounting hole, a fixing means for fixing to the door inner panel is provided on the door inner panel side, that is, on the inner side wall portion.

As the fixing means, for example, mounting holes formed in an embossed shape are provided at two places on the left and right sides.
The attachment hole may be screwed and fixed to the door inner panel, and a locking hook having an L-shaped cross section whose tip is bent downward is formed on the outer surface of the back side wall portion, and is opened on the door inner panel. This locking hook may be engaged and fixed to the formed elongated opening.

A U-shaped spring nut is fitted into a mounting base formed on the inner surface of the armrest of the door trim, and the bottom surface of the pull handle is fixed to the door trim via screws.

As is apparent from the above construction, the bottom surface of the pull handle is fixed to the mounting base provided on the inner surface of the door trim with screws, and the rear side wall of the pull handle is screwed or directly engaged by fastening. Since it is fixed to the door inner panel, the conventional mounting bracket can be eliminated and the nonwoven fabric conventionally used for preventing low-pitched sound can also be eliminated.
