[0017]
Since the flexible tongue has a claw contact portion, the claw is smoothly inserted, and when the claw is inserted, the claw is sandwiched between the flexible tongue and the wall of the claw engagement hole. The hole cover does not rattle.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0019]
FIG. 1 is a diagram showing the right half of the front bumper as viewed from the front. A lamp hole 2 for attaching a fog lamp is provided below the bumper 1. FIG. 2 is a view of the lamp hole cover 3 (hereinafter simply referred to as a cover) viewed from the front side (a view viewed from the outside of the vehicle body when the cover 3 is attached to the lamp hole 2). 3 is a cross-sectional view taken along line AA in FIG. FIG. 4 is a perspective view of the lamp hole 2 as viewed from the vehicle body side. FIG. 5 is a view in which the place where the claw 13 is to be inserted into the claw engagement hole 7 is viewed obliquely from the outside of the vehicle body. FIG. 6 is a cross-sectional view in the middle of the nail 13 being inserted, and FIG. 7 is a cross-sectional view in which the nail 13 has been completely inserted.
[0020]
In the mounting structure of the present embodiment, the cover 3 shown in FIG. 2 is brought close to the lamp hole 2 shown in FIG. 4 from the vehicle body side, and the claw 13 of the lamp hole 2 is inserted into the claw engaging hole 7 of the cover 3. It is to be fixed. Then, as shown in FIG. 7, the closing portion 4 protruding outward from the vehicle body closes the lamp hole 2.
[0021]
As shown in FIG. 4, four claws 13 and three positioning tongues 14 are provided toward the vehicle body side at the peripheral edge 2a of the lamp hole 2 of the bumper. The positioning tongue piece 14 is provided between the claws 3. The nail | claw 13 is formed with the flexible base 13a and the hook-shaped part 13b formed in the front-end | tip of this base 13a. Although the lamp hole 2 is opened in a circular shape here, the shape of the opening is determined by the shape of the lamp to be mounted, so the shape is not limited to a circular shape, and may be a square or an ellipse. Further, the number of the claws 13 and the positioning tongues 14 need only be sufficient to fix the cover 3. It is preferable that the number of the claws 13 and the positioning tongues 14 is two or more because the cover 3 is firmly fixed and positioning is easy.
[0022]
Next, the cover 3 shown in FIGS. 2 and 3 will be described. Most of the cover 3 is a closing portion 4 that closes the lamp hole 2, which protrudes outside the vehicle body when inserted into the lamp hole 2 and is inserted into the lamp hole 2. In FIG. And projecting vertically upward. A flange portion 5 extends outwardly from the closing portion 4 in a bowl shape, and a peripheral wall portion 6 stands on the outer peripheral edge of the flange portion 5. The peripheral wall portion 6 is erected in substantially the same direction as the direction in which the closing portion 4 protrudes.
[0023]
A claw engaging hole 7 and a positioning hole 9 are opened in the flange portion 5. The claw engaging holes 7 are provided at the same four positions as the claw 13 at positions corresponding to the claw 13 of the lamp hole 2, and the positioning holes 9 are positioned at positions corresponding to the positioning tongue pieces 14 of the lamp hole 2. The same three places as the piece 14 are provided. A pair of slits 15 are provided in the peripheral wall portion 6 adjacent to the claw engaging hole 7 from the claw engaging hole 7 to the middle of the peripheral wall portion 6 as shown in FIG. A flexible tongue 8 is formed between them. That is, the pair of slits 15 are circumferentially formed in the direction in which the peripheral wall 6 is erected from the claw engaging hole 7 to the middle of the peripheral wall 6 so that the flexible tongue 8 whose tip faces the claw engaging hole 7 is formed in the peripheral wall 6. It is formed at intervals in the direction. As shown in FIG. 3, the thickness of the flexible tongue 8 decreases on the surface facing the lamp hole peripheral edge 2 a of the bumper from the flexible tongue base 20 toward the flexible tongue tip 12. The claw contact portion 10 is inclined as described above. The flexible tongue base 20 is a portion where the claw contact portion 10 starts from the flexible tongue 8, and the flexible tongue 8 projects rightward in the drawing from the flexible tongue 8 toward the flexible tongue tip 12. The wall thickness (thickness between the top and bottom in the figure) is getting smaller.
[0024]
The process of fitting the claw 13 into the claw engagement hole 7 and engaging it will be described with reference to FIGS. 3, 4, 5, 6, and 7. FIG. FIG. 5 shows a state of the claw 13, the claw engagement hole 7, and the flexible tongue 8 before being fitted. The cover 3 is moved in the direction of the arrow and fitted into the lamp hole 2. In FIG. 3, the claw 13 is inserted from the upper side of the figure, but at first, the hook-shaped portion 13 b of the claw 13 abuts on the portion of the claw abutting portion 10 having a small distance from the peripheral wall portion 6. As the pin is inserted, the base 13a of the claw 13 is bent, and the hook-shaped portion 13b approaches the closed portion 4 side, that is, the center side of the circular cover 3 while sliding on the claw contact portion 10. At this time, the flexible tongue 8 is gradually bent to the left in FIG. 3, and the distance between the flexible tongue tip 12 and the wall 11 of the claw engagement hole 7 facing the flexible tongue tip 12 is increased. It gets bigger. In the state of FIG. 6, the hook-shaped portion 13 b of the claw 13 is in contact with the wall 11 of the engagement hole, and the flexible tongue 8 is bent most, but at this time, the base portion 13 a of the claw is also bent most. Since both the claw 13 and the flexible tongue 8 bend at the time of insertion, the stress at the time of insertion does not concentrate on one member (the claw 13), and either one can be prevented from being broken or scraped.
[0025]
When the claw 13 is completely inserted, the claw 13 is engaged with the surface of the flange portion 5 on the vehicle body side as shown in FIG. 7, and the bending of the claw 13 and the flexible tongue 8 is eliminated. The distance between the flexible tongue tip 12 and the wall 11 of the claw engagement hole 7 facing the flexible tongue tip 12 is based on the thickness of the claw base portion 13a between which both are originally sandwiched in FIG. Since they are small, they sandwich the nail base 13a so that the cover 3 does not rattle.
[0026]
When removing the cover 3 from the lamp hole 2, it is only necessary to operate from the back side of the bumper 1 to remove the engaging claw 13 from the claw engaging hole 7 and to remove the cover 3, so there is no need to use a blade. It is safe.
[0027]
The shape of each part shown in this Embodiment is an example, and this invention is not limited to this. For example, the claw 13 and the flexible tongue 8 may be provided with a curved surface portion so as to be smoothly bent, and the entire outer periphery is not provided without providing the peripheral wall portion 6 on a part of the outer periphery of the flange portion 5 as in the present embodiment. May be provided.
