Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle grill mounting structure which is mounted on a front portion of an automobile.

[0002]

2. Description of the Related Art As a recent tendency, a grill for a vehicle is divided into two parts, one of which is plated and the other is painted. The reason is that plating the integrated grill and then partially painting it will increase the cost of plating.
Also, it is difficult to satisfy the coating film performance of the masked coating portion. The structure for mounting the two-division type vehicle grill is almost the same as the structure for mounting the conventional vehicle integrated grill on the bumper or other mounting members, and is mounted by engaging the engaging projections and the engaging claws. However, the current situation is that they are attached with a tapping screw or a resin clip.

For example, in the case of engaging the engaging projection and the engaging claw, Japanese Patent Laid-Open No. 2001-180400 discloses that the engaging projection 11 is attached to the grill in order to assemble the grill to the bumper as shown in FIG. There is disclosed a method in which the bumper is provided with a flexibly deformable engagement claw 7 and the engagement projection 11 of the grill is engaged with the engagement claw 7 of the bumper. Insertion hole 10 into which the engaging projection 11 is inserted on the end face of the bumper
There is an engaging projection 7b having a triangular cross section so as to face the insertion hole 10, and the engaging projection 11b is provided on the grill.
There is an engaging protrusion 12.

Further, in Japanese Patent Application Laid-Open No. 10-194061, as shown in FIG. 10, mounting portions 20 and 22 are integrally formed on the upper and lower portions of the radiator grill 10, and the upper mounting portion 20 further includes Elastically deformable claw portion 20b protruding upward from the substantially horizontal upper wall portion 20a of the upper mounting portion 20.
Is integrally formed, and the lower mounting portion 22 is integrally formed with an elastically deformable claw portion 22b protruding downward from a substantially horizontal lower wall portion 22a of the mounting portion. Headlamp 1
A locking portion 30 is formed on the second locking portion 30, and each locking portion 30 has an opening portion 30a for receiving the mounting portions 20 and 22, and a frame portion 30b extending rearward from the periphery of the opening portion 30a. The upper mounting portion 20 is inserted into the opening 30a, and the elastically deformable claw portion 20b is engaged with by engaging with the notch 30c provided in the frame portion 30b.

[0005]

However, in the conventional grill mounting structure such as the above-mentioned Japanese Patent Laid-Open No. 2001-180400, thermal expansion and contraction occur due to changes in the outside air temperature. However, there is a sufficient risk that the engaging claw 7 is pushed out and the engaging force is lost, resulting in looseness in the engagement. Also, the engaging claw 7
However, there is also a problem that the engaging structure becomes large by having a pair of engaging convex portions 7b having a triangular cross section so as to face each other.

Further, in the case of Japanese Patent Laid-Open No. 10-194061, when the grill is plated, the elasticity of the engaging portion 22b may be lost and the grill may not be bent. That is, since the plating film is formed on the surface of the engagement portion 22b, the elasticity of the engagement portion 22b is hindered by the presence of the plating layer, and there is a possibility that smooth engagement cannot be achieved. The present invention has been made in view of the above problems, and an object of the present invention is to provide a mounting structure for a vehicle grill, which has a simple and compact shape and can reliably maintain an engaged state.
