Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a mounting structure of a wheel protector that borders a semicircular wheel arch formed on a fender panel that constitutes a wheel house of a vehicle.

<< Prior Art >> In a wheel arch provided with a protector of this type, the protector is usually attached along the inner peripheral edge of a flange formed to project inside the wheel arch and fixed by a screw.

However, in this screw fixing work, since the hands are inserted into the flange and the screws are screwed in, the whole work is troublesome, and since there are many attachment points, the efficiency of the attachment work is poor.

Therefore, conventionally, for example, as shown in Japanese Utility Model Laid-Open No. 60-47656, a plurality of mounting holes are formed in the periphery of the wheel arch of the fender panel, and elastically expandable caps are fitted into the mounting holes. On the other hand, a decorative piece of the protector is formed in a rail shape, a clip is previously fitted inside the decorative piece, and the clip is fitted into the cap to elastically expand the cap, and the clip and the cap together with the protector are attached to the fender panel. It is fixed to.

In this technique, the protector is fixed just by pressing the protector against the wheel arch, so that the work efficiency is high.

<Problems to be solved by the invention> However, in this mounting structure, since the shaft portion of the cap and the clip protrudes inside the wheel house, the tire bounces off pebbles when driving on a bad road. When it was raised, it often collided with the projecting portion, and the shaft portions of the cap and the clip were broken, and the engagement between the both was released or dropped.

Further, in this structure, the protector is composed of a rail-shaped decorative piece and a portion which is integrated in a bent state at one side of the decorative piece and abuts on the inner peripheral edge of the flange. Since one side of the decoration is fixed to the fender panel, it is not directly connected to the inner peripheral edge of the flange, but only makes contact, so the bonding force as a member that borders the inner peripheral edge of the wheel arch is weak. It was

This invention was made in order to eliminate the above drawbacks, the amount of protrusion to the inside of the wheel house is small,
There is no breakage due to flipping up of pebbles, etc.
Moreover, it is an object of the present invention to provide a mounting structure for a fender protector having a high coupling force with respect to a wheel arch.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention relates to a flange formed on the inside of a semicircular wheel arch forming a wheel house of a fender panel and fixed to the flange. In a thing provided with a fender protector edging a wheel arch: The protector is provided with a sandwiching piece having a substantially U-shaped cross section for sandwiching the flange, and integrally extending at one end of the sandwiching piece, A clip that is composed of a decorative piece that borders the outside of the inner peripheral edge and that is fitted through the flange and the sandwiching piece from the inner peripheral side of the wheel arch and the clip that is fitted to the inward protruding end of the clip. The fixing ring is fixed to the wheel arch via a fixing ring that is fixed in an inserted state, and the fixing ring is a recess formed on one side of the sandwiching piece. A shaft hole is opened, is fitted to the shaft outer circumference of the clip in the center of the flat rectangular plate member disposed,
The guide groove is formed so as to expand from one side of the shaft hole, and a retaining piece that protrudes inside the guide groove is provided for retaining.

<Operation> According to the above configuration, after the protector is attached along the wheel arch, the clip is inserted through the sandwiching piece and the flange of the wheel arch, and then the fixing ring is attached from the side of the inner protruding end of the clip. When inserted, the ring is elastically fitted to the shaft portion to prevent the ring from being pulled out, and is fixed in the rotation preventing state by the groove. And by this combination,
