Preferred embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention, in which an instrument 1 is an object to be mounted, and has an installation hole 11 formed therein. An attachment component 2 such as an interior material is attached to the attachment hole 11 using a component attachment clip 3 (hereinafter, simply referred to as a clip).

The mounting part 2 has a plate-like projection 21 made of resin.
Is provided, and the protrusion 21 is locked in the mounting hole 11 via the clip 3. The body of the clip 3 is formed in a substantially V-shape by folding a spring plate, and the retaining portions 32, 32 inclined inward at portions near the open ends of the pair of opposing pieces 31, 31 of the clip body, respectively. , And two pairs of locking portions 33 are formed at the intermediate portion between the open end side and the folded end side of each of the opposing pieces 31, 31. Each locking part 33
Are formed in a sharp shape that is inclined inward toward the folded end side and can bite into the protrusion 21.

As shown in FIG. 1 (B), the locking portion 33 formed on one opposing piece 31 and the locking portion 33 formed on the other opposing piece 31 are arranged in the width direction of the opposing pieces 31, 31. In addition, as shown in FIG. 1 (A), the two opposing pieces 3
1, 31 overlap in the facing direction.

As shown in FIG. 1B, in this embodiment, a pair of locking portions 33, 33 formed on both side edges in the width direction of one opposing piece 31, respectively, The portion 33 is formed on the inner side in the width direction of the opposing piece 31 (the left-right direction in FIG. 1B), and the other locking portion 33 is formed on the outer side in the width direction of the opposing piece 31. The other opposing piece 31 is illustrated as being symmetrical with a pair of locking portions 33 formed on both side edges in the width direction of the one opposing piece 31, respectively. .

A plurality of projections 21 are formed at predetermined intervals on the back surface of the mounting component 20, and the number of clips 3 corresponding to the number of the projections 21 is set. The mounting holes 11 formed in the instrument panel 1 are formed by drilling in advance corresponding to the set numbers of the protrusions 21 and the component mounting clips 3.

FIG. 1A and FIG.
As shown in (B), a U-shaped portion 34 is formed at a portion where the spring plate is folded. The U-shaped portion 34 is bent to have a substantially U-shaped cross section. In the present embodiment, the U-shaped portion 34 is formed.
A rib 37 for preventing the facing piece 31 from bulging outward when assembled is integrally formed. This rib 37
It functions to prevent the facing piece 31 from bulging outward when assembled. Further, as shown in FIG. 1, in the present embodiment, the ribs 37 except for the bottom surface 35 of the U-shaped portion 34
It is formed on both sides 36, 36 of the character-shaped part 34, respectively.

Further, the pair of locking portions 33, 33 are located between the U-shaped portion 34 and the opposing piece 31 and face the both sides of the U-shaped portion 34 and the opposing piece 31 in the width direction. Is formed.

FIG. 3 shows a specific configuration example of the projection 21 according to the present embodiment. In this example, the projection 21 is formed so as to protrude from the attachment component 2 in a substantially H-shaped cross section. A pair of side walls 23 are integrally formed at both ends of the main body 22 in the width direction (the direction perpendicular to the plate thickness). In this example, since the protrusion 21 is formed in a substantially H-shaped cross section, the protrusion 2
Since the second moment of area as a whole is large and the rigidity is high, the protrusion 21 is attached to the mounting hole 11 of the mounting object 25.
When assembling, the possibility that the protruding portion 21 comes off from the mounting reference position is reduced, and the assembling accuracy is improved.

Next, the assembling procedure and operation of the above embodiment will be described. First, the protrusion 21 of the mounting part 2 is
Is press-fitted from the open end side to the folded end side. According to this, the locking portions 33, 33 bite into both sides of the projection 21, and the projection 21 is held by the clip 3.

Next, the clip 3 is press-fitted into the mounting hole 11 of the instrument panel 1. According to this, the interval between the pair of opposing pieces 31, 31 is narrowed, and the locking portions 33, 3
3 penetrates deeper into the protrusion 21, and when the retaining portions 32, 32 escape from the mounting hole 11, the gap between the opposing pieces 31, 31 increases, and the retaining portions 32, 32 form the opening edge of the mounting hole 11. And the clip 3 is prevented from being pulled out of the mounting hole 11. At this time, the locking portions 33, 33 slightly move outward in the direction in which the pair of opposing pieces 31, 31 are opposed to each other.
Since the engaging portions 33 and 33 are formed so as to overlap with each other in the facing direction of the engaging portions 1 and 31, the engaging portions 33 and 33 are surely maintained in a state of being cut into the protruding portion 21. Thus, the projection 21 is securely locked in the mounting hole 11 via the clip 3. In addition, the assembling error of the attachment part 2 is caused by the bending of the opposing pieces 31, 31, as shown in FIG.
Is absorbed by the tilt in the direction of the arrow.

After the mounting part 2 is assembled and fixed to the instrument panel 1, for example, when the mounting part 2 is removed and the inside is inspected, the mounting part 2 is gripped and the mounting hole of the instrument panel 1 is held. When a force is applied in a direction in which the projection 21 is pulled out from the projection 11, the clip 3 integrated with the projection 21 is elastically deformed in the opposite direction to that at the time of assembly, and passes through the mounting hole 11. The attachment part 2 can be easily removed from the instrument panel 1. Then, after removing the attachment part 2, each of the protrusions 2
When it is necessary to remove the clip 3 from the projection 1, the upper ends of the pair of opposing pieces 31, 31 of the clip 3 are pressed and deformed until they contact the projection 21. The engagement is released, and the clip 3 can be removed from the projection 21.

In this embodiment, the pair of locking portions 33 formed on the pair of opposing pieces 31, 31 as described above,
Since the clips 33 are arranged symmetrically to each other as described above, regardless of the direction in which the clip 1 is attached to the projection 21, the locking portions 33 are always at the same position.
1 can be assembled without worrying about the direction of the clip 1, and there is an advantage that the workability of assembling the projection 21 is improved.

When the opposing pieces 31, 31 are pressed into the mounting holes 11 of the instrument panel 1, the mounting holes 1
When the pair of opposing pieces 31 are sandwiched by the unit 1, an external force is exerted so that the U-shaped part 34 of the clip 3 and the pair of opposing pieces 31 expand outward with the pair of locking portions 33 as fulcrums. However, in the present embodiment, the U-shaped portion 3
By forming the ribs 37 on the pair 4, the pair of opposed pieces 31 can be effectively prevented from bulging outward when assembled, and
3 can be firmly clamped to further increase the biting force of the locking portion 33 into the protruding portion 21 and to surely prevent the locking portion 33 from coming off.

In this embodiment, the ribs 37 are formed on both sides 3 of the U-shaped portion 34 except for the bottom surface 35 of the U-shaped portion 34.
6, the stiffness of the U-shaped portion 36 is high at both side portions 36 and becomes normal at the bottom portion 35. Therefore,
When the projection 21 of the mounting part 2 is pressed and fitted into the clip 3, the tip of the projection 21 is pressed against the normally rigid bottom surface 35, so that the tip of the projection 21 is prevented from being deformed. Can.

Furthermore, when the projection 21 is pressed and inserted into the clip 3, the insertion direction of the projection 21 is regulated by the both sides 36 having high rigidity, so that the projection 21 can be inserted at an accurate position. As a result, the positional accuracy at the time of assembly can be significantly improved.

In this embodiment, the locking portion 33 is located between the U-shaped portion 34 and the opposing piece 31, and the U-shaped portion 34
And since it is formed facing both side edges in the width direction of the opposing piece 31, it is possible to maximize the distance between the locking portions 33 facing each other in the width direction for each pair of opposing pieces 31, 31. As a result, the projections 21 are widely separated and the projections 21 are clamped. Therefore, even if the entire clip 3 is relatively small, the projections 21 are pressed and fitted to an accurate position without being inclined at the time of assembly. Insertion is possible, and stability after assembly is increased.

Further, since each locking portion 33 is set to an optimal acute angle so as to be on the same slope as the inclined portion 38, it can bite into the predetermined position of the protrusion 21 more firmly, and can be securely engaged. Can be effectively prevented from coming off.

Further, in this embodiment, since the locking portions 33 are provided as described above, the following operation and effect can be obtained. That is, after the locking portions 33 have been bitten into the protrusions 21 at the time of assembly, they are fixed to the protrusions 21 from the mounting holes 11 of the workpiece 1 at the time of inspection of the inside of the mounting component 2 or the like. In the state, the clip 3 is removed together, the clip 3 is detached from the projection 21, and when the same mounting part 2 is reassembled after the inspection, the same clip 3 is reused for the projection 21. By using the clip 3 by rotating the clip 3 by 180 degrees around the rotation axis center with respect to the last time,
It is possible to re-use because each locking part 33 can bite into a position where there is no scar, avoiding the biting mark left by 3, so that it is possible to reuse and secure the biting strength of each locking part 33 as before. There is an advantage that can be.

Further, in this embodiment, the pair of ribs 37, 37 are provided in the width direction of the U-shaped portion 34, so that the pair of opposing pieces 31 can be effectively prevented from bulging outward when assembled. Thus, the locking portion 33 can be firmly clamped to enhance the biting force of the locking portion 33 into the protrusion 21, thereby further improving the effect of reliably preventing detachment.

Since the other structure is the same as that of the first embodiment, the same operation and effect as those of the first embodiment can be obtained. In the first embodiment, the rib 37 is moved by 1 in the width direction of the U-shaped portion 34. In the second embodiment, two ribs 37 are formed in the width direction of the U-shaped portion 34. However, the present invention is not limited to this.
