Specifically, the fitting member of the bumper 10 is the through hole 20 shown in FIG. 3, and the fitting member of the grill 12 is the insertion piece 22 shown in FIG. By fitting the through hole 20 and the insertion piece 22 together, the lower edge 12a of the grill 12 is fixed to the bumper 10, that is, the lower edge 16c of the opening 16.

Next, the through hole 20 and the insertion piece 22 which are fitting members will be described. The opening 16 of the bumper 10 is provided with a vertical wall 24 that rises upward from the lower edge 16c along the lower edge 16c of the opening 16 as shown in FIG.
The through holes 20 are provided at two places on the vertical wall 24 of the lower edge 16c as shown in FIG. 1, and are formed so as to penetrate the vertical wall 24 along the longitudinal direction of the vehicle 14 as shown in FIG. Has been done.

As shown in FIG. 1, the grill 12 is wholly formed of a plate-like member and has a ventilation part 28 formed in the center. The ventilation part 28 is formed of a lattice, and an insertion piece 22 which is a fitting member of the grill 12 is provided at a lower edge 12a of a lower part of the ventilation part 28. The insertion pieces 22 are provided on the back surface side of the grill 12 at two positions along the lower edge portion 12 a of the grill 12 at positions corresponding to the through holes 20.

As shown in FIG. 2, the insertion piece 22 basically has a rectangular shape. As shown in FIG. 3, the insertion piece 22 has a length sufficient to penetrate the through hole 20 and project to the rear of the through hole 20 when the grill 12 is assembled to the opening 16 of the bumper 10, as shown in FIG. The thickness and width are such that a slight gap is formed between the through hole 20 and the through hole 20 in a state where the through hole 20 is inserted.

As shown in FIG. 2, the insertion piece 22 has an insertion piece body portion 30, a tip portion 32, and a hinge portion 34. The hinge portion 34 is formed thinly around its periphery and extends in the vehicle width direction.
L-shaped notches 36 are provided at both left and right ends of the hinge portion 34. The notch 36 includes a first notch line 36a extending from the left and right ends of the insert piece 22 toward the center of the insert piece 22, and a second notch line extending from the end of the first notch line 36a toward the rear of the vehicle 14. The second cutout line 36b is connected to the left and right ends of the hinge portion 34, respectively.

As a result, the insert piece 22 is divided into the insert piece body portion 30 and the tip end portion 32 by the hinge portion 34 and the notch 36. The tip end portion 32 is formed with an extension portion 38 that projects from the both ends in the vehicle width direction beyond the hinge portion 34 toward the front of the vehicle.
Therefore, when the tip portion 32 is bent along the hinge portion 34, the insertion piece 22 extends toward the side opposite to the bending direction of the tip portion 32 about the hinge portion 34 as shown in FIGS. To deploy. The extension portion 38 has such a protruding amount that it faces the back surface of the vertical wall 24 when the tip portion 32 is bent.

Next, the operation and effect of the fitting structure will be described. The grill 12 is attached to the opening 16 provided in the bumper 10 from the front of the vehicle 14. The insertion piece 22 penetrates the through hole 20, and the tip portion 32 (including the extension portion 38) protrudes from the through hole 20 to the back side of the bumper 10, that is, to the rear of the vehicle 14, as shown in FIG. 3.

A bolt is passed through the bolt hole 19 (see FIG. 1) from the back side of the bumper 10 (mounting member 16a or the like) to fix the grill 12 and the bumper 10 with the bolt.
Then, the distal end portion 32 of the insertion piece 22 passed through the through hole 20 is bent downward by the hinge portion 34 as shown in FIG. Then, the tip portion 32 is bent downward on the back surface side of the bumper 10 as shown in FIG. 4, and the extension portion 38 is deployed above the through hole 20.

Therefore, the insertion piece 22 forms a so-called T-shape by the insertion piece body portion 30, the tip portion 32, and the extension portion 38, and engages with the back surface side of the bumper 10. As a result, the lower edge 12a of the grill 12 is fitted into the opening 16 (lower edge 16c) of the bumper 10.
Even if an external force T (see FIG. 4) that pushes the grill 12 forward of the vehicle 14 acts during traveling, the tip portion 32 bent downward and the upper portion 32 as shown in FIGS. Since the extended portion 38 developed on the upper side and the lower side of the through hole 20 hangs, the insertion piece 22 does not easily come out of the through hole 20. Therefore, even if a large external force T that pushes the grill 12 forward is applied, the fitting between the bumper 10 and the grill 12 is prevented from being easily disengaged.

Further, since the insertion piece 22 is only bent at the hinge portion 34, the grill 12 can be easily attached to the opening 16 of the bumper 10.

Next, another embodiment of the present invention will be described. In this embodiment, as shown in FIG. 7, a first projection 40 is provided on the vertical wall 24, and a second projection 42 is provided on the extension 38. The other parts are the same as those in the above-described embodiment, and the same parts are denoted by the same reference numerals and will not be described.

The first protrusion 40 is provided on the back surface of the vertical wall 24 so as to project to the rear side of the vehicle 14. The first protrusion 40 is provided on the side where the tip portion 32 is bent, that is, in the lower portion of the through hole 20 in the present embodiment, in a region facing the bent tip portion 32. It is preferable that the first protrusion 40 has a protrusion amount such that the tip 32 is slightly touched with the tip 32 when the tip 32 is bent substantially at right angles to the insertion piece body 30.

The second protrusion 42 is provided on the surface facing the vertical wall 24 when the tip portion 32 is bent and the extension portion 38 is expanded, that is, on the lower surface of the extension portion 38 in the present embodiment. Similar to the height of the first protrusion 40, the protrusion amount of the second protrusion 42 is such that when the extension portion 38 is bent substantially at a right angle to the insertion piece main body portion 30, the second protrusion 42 is lightly touched with the back surface of the vertical wall 24. preferable.

Further, the second protrusion 42 is formed in a position and in a shape such that the second protrusion 42 comes into contact with the vertical wall 24 or the like and does not hinder the expansion when the tip portion 32 is bent with respect to the insertion piece body portion 30. In the present embodiment, the tip of the second protrusion 42 is rounded so that the deployment is not hindered. In addition, by providing the second protrusion 42 on the hinge portion 34 side with respect to the tip of the extension portion 38, it is possible to prevent the development from being hindered.

In the through hole 20, a groove portion that extends in the front-rear direction is provided from the front end to the rear end of the through hole 20 in accordance with the position where the second protrusion 42 passes. Accordingly, the tip portion 32 can be inserted without increasing the size of the through hole 20 (width in the vertical direction), and the rattling of the grill 12 with respect to the bumper 10 can be suppressed.

In this embodiment, when the tip 32 is bent after the insertion piece 22 is passed through the through hole 20, the tip 32 and the extension 38 are attached to the vertical wall 24 via the first protrusion 40 and the second protrusion 42. Since they face each other, rattling with the vertical wall 24 can be suppressed.
In the insertion piece 22, it is necessary to set the hinge portion 34 to the rear side of the vehicle 14 from the back surface of the vertical wall 24 so that the extension portion 38 can smoothly rotate behind the vertical wall 24, and therefore, the bent tip is bent. A gap is formed between the vertical wall 24 and the portion 32 or the extension portion 38. The gap easily causes rattling, but by providing the first protrusion 40 and the like, the rattling can be reduced and the grill 12 can be stably fixed to the bumper 10 in the present embodiment.

As described above, according to the fitting structure according to the present invention, the exterior component can be easily attached to the bumper 10 and the fitting can be prevented from coming off. Further, it is possible to suppress the occurrence of rattling after the fitting.
The above embodiment is an example, and the present invention can be implemented by variously changing the specific mode. Further, although the front bumper and the under grill are fitted to each other in the embodiment, the present invention may be applied to members other than the front bumper and the grill. Although the insertion piece 22 is bent downward, it may be bent upward. Alternatively, the insertion piece may be provided on a member extending in the vertical direction, and the insertion piece may be bent in either the left or right direction.
