There is known a mounting structure that is fitted into a formed opening and fixed by being screwed to the edge of the opening.

[0003]

[Problems to be solved by the device]

 However, in the mounting structure of the above-mentioned publication, the grill component is screwed to the opening edge of the bumper, so that it has the advantage that it is difficult to come off, but on the contrary, there is the problem that it takes time for the mounting work.

Therefore, it is conceivable to attach the fitting to the opening of the bumper by engaging the engaging claw formed on the fitting side with the engaging groove formed on the bumper side.

However, in this case, contrary to the case of the above-mentioned publication example, the mounting work is simple, but when the bumper is deformed by an external force such as an impact, the engaging claw is disengaged from the engaging groove and fitted. There is a problem that objects fall out of the bumper opening.

The present invention has been made in view of the above point, and an object thereof is to add a separate member in association with the engaging claw used in the latter case described above so that the fitting state can be improved. It is intended to stabilize and prevent the mating object from falling off due to external force such as impact, and at the same time to ensure easy installation workability.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the solution means of the present invention is a mounting structure in which a fitting is fitted into an opening of a bumper to mount a fitting wall having an insertion hole at a tip end on an opening edge of the bumper on a rear surface side. Project toward. On the other hand, when the fitting object is pushed in, a locking piece that is locked to the tip portion of the mounting wall and a projection piece that is inserted into the insertion hole are projectingly provided on the fitting object at the same base portion. That's what I did.

[0008]

[Action]

 With the above-described structure, in the present invention, the engaging piece pushing operation causes the engaging piece locking piece to be locked to the tip of the mounting wall protruding from the opening edge of the bumper, and Since the projecting piece that also has the same base as the projecting piece is inserted into the insertion hole of the mounting wall, the mating object can be mounted in the opening of the bumper only by pushing it in, which facilitates the mounting work.

Further, when the bumper is bent by the action of an external force such as an impact, the external force is transmitted to the protruding piece of the fitting and the protruding piece is bent, and this bending force is transmitted to the locking piece via the base portion. Since the locking piece follows the projecting piece and bends in the same direction, the locking piece does not separate from the tip of the mounting wall, so that the fitted state is stable and the falling of the fitting is prevented.
