<Clip usage instructions>
The clip CP in FIG. 1A includes a first mounting example (see FIG. 4) for mounting the insulator IS to the vehicle body panel BP using the stud bolt SB of the vehicle body panel BP, and a mounting hole H2 of the vehicle body panel BP. It is possible to flexibly cope with both of the second mounting examples (see FIG. 5) in which the insulator IS is mounted on the vehicle body panel BP by utilizing the insulator IS.

In both the first and second mounting examples, the following description is based on the assumption that the insulator IS is provided with a through-hole H1 penetrating the front and back surfaces. Explain the work.

<< About the first installation example >>
In the first mounting example, that is, when the insulator IS is attached to the vehicle body panel BP using the stud bolt SB of the vehicle body panel BP, the insulator IS is first set on the vehicle body panel BP. In this set operation, the stat bolt SB of the vehicle body panel BP is assumed to be disposed in the through hole H1 of the insulator IS.

After the above setting work is completed, next, the tip CP1 of the clip CP (specifically, the side where the stud bolt guide 5 and the mounting hole guide 6 are provided) is opposed to the tip of the stud bolt SB. The clip head 2 of the clip CP is pressed in the direction of the vehicle body panel BP with a predetermined force.

As a result, as shown in FIG. 4, the clip body 1 of the clip CP is fitted in the through hole H1 of the insulator IS, the stud bolt SB of the vehicle body panel BP is inserted inside the clip body 2, the clip A state in which the head 2 is hooked and engaged with the edge surface of the through hole H1, a state in which the outer claw 4 is in contact with or bites into the inner surface of the through hole H1, and an inner claw 3 is attached to the outer peripheral thread portion of the stud bolt SB. By being in the engaged state, the operation of attaching the insulator IS to the vehicle body panel BP is completed.

In the first mounting example, the clip CP is positioned and fixed with respect to the insulator IS when the outer claw 4 comes into contact with or bites into the inner surface of the through hole H1 as described above.

In the first mounting example, the mounting strength of the insulator IS can be adjusted by shifting the engagement position P1 between the inner claw 3 and the outer peripheral thread portion of the stud bolt SB in the vertical direction.

For example, when the clip head 2 of the clip CP is further pressed from the state shown in FIG. 4, the engagement position P1 is shifted downward, so that the mounting strength of the insulator IS is improved. On the contrary, when the engagement position P2 is shifted upward, the mounting strength of the insulator IS is set to be relatively low.

By the way, in the first mounting example, when the tip CP1 of the clip CP is opposed to the tip of the stud bolt SB as described above, the clip CP is inclined with respect to the stat bolt SB. Alternatively, the clip CP and the stud bolt SB may be relatively displaced in the lateral direction.

In the first mounting example, when the inclination or displacement as described above occurs, the tip of the stat bolt SB abuts on the guide surface 5A of the stat bolt guide 5, and the tip of the stat bolt SB that abuts is By sliding along the guide surface 5 </ b> A, the clip body portion 1 is guided in the inner direction from the lower opening.

Therefore, the troublesome work such as correction of the inclination and displacement as described above is not necessary when the insulator IS is attached by the clip CP as in the first attachment example. In this respect, the insulator IS is attached. The work is easy.

<< About the second case >>
In the second mounting example, that is, when the insulator IS is mounted on the vehicle body panel BP using the mounting hole H2 of the vehicle body panel BP, the insulator IS is set on the vehicle body panel BP as in the first mounting case described above. However, in this set operation, it is assumed that the mounting hole H2 of the vehicle body panel BP is disposed directly below the through hole H1 of the insulator IS.

After the above setting operation is completed, the clip head 2 of the clip CP is set in a direction toward the vehicle body panel BP with the tip CP1 side of the clip CP facing the upper end opening of the mounting hole H2 of the vehicle body panel BP. Press with force.

Then, first, the attachment hole guide 6 of the clip CP is pushed into the attachment hole H2 of the vehicle body panel BP. At this time, the attachment hole guide 6 passes through the attachment hole H2 by being elastically deformed in a contracting direction by a reaction force received from the inner edge side of the attachment hole H2. Similarly, the stat bolt guide 5 is elastically deformed to pass through the mounting hole H2. Further, the lowermost outer claw 4 (blade 41) is also elastically deformed and passes through the attachment hole H2.

As described above, the outermost nail 4 (blade 41) in the lowermost stage after passing through the attachment hole H2 returns to its original state due to its elastic restoring ability, and is in a state of being hooked and engaged with the edge surface of the through hole H1. This completes the operation of attaching the insulator IS to the vehicle body panel BP.

At this time, the outer CP 4 (blade 42, blade 43) other than the lowermost outer claw 4 (blade 41) comes into contact with or bites into the inner surface of the through hole H1, so that the clip CP for the insulator IS is obtained. The positioning is fixed.

In the second mounting example, when the clip head 2 of the clip CP is pressed more strongly, the outer claw 4 (blade 42) in the second step from the bottom passes through the mounting hole H2 of the vehicle body panel BP and the mounting hole H Therefore, the mounting strength of the insulator IS with respect to the vehicle body panel BP is improved.

Further, in the second mounting example, when the thickness of the insulator IS is reduced, the outer claw 4 (42) in the second stage from the bottom or the outer claw 4 (43) in the uppermost stage is the mounting hole H2 of the vehicle body panel BP. A predetermined attachment strength can be obtained by passing through and engaging the rear surface of the edge of the attachment hole H.

By the way, in the second mounting example, when the tip CP1 side of the clip CP is opposed to the upper end opening of the mounting hole H2 of the vehicle body panel BP as described above, the clip is clipped with respect to the central axis of the mounting hole H2. There are cases where the CP is inclined and the clip CP and the mounting hole H2 are relatively displaced in the lateral direction.

In the second mounting example, when the inclination or the deviation occurs as described above, the clip body portion when the mounting hole guide 6 of the clip CP is pushed into the mounting hole H2 of the vehicle body panel BP as described above. 1 is guided along the guide surface 61A of the mounting hole guide 6 toward the center of the mounting hole H2.

Therefore, in the mounting operation of the insulator IS by the clip CP as in the second mounting example, the troublesome work such as correction of the inclination and displacement as described above is unnecessary, and in this respect, the mounting operation of the insulator IS. Is easy.

In the first and second mounting examples described above, the insulator CP is set on the vehicle body panel BP, and then the clip CP is fitted into the through hole H1 of the insulator IS set. A piece in which CP is fitted in the through hole H1 of the insulator IS in advance may be set on the vehicle body panel BP.

In the clip CP of the embodiment described above, as a specific configuration, when the stud bolt SB for attaching the insulator IS is present in the vehicle body panel BP, the inner claw 3 is the outer peripheral thread portion of the stud bolt SB. When the mounting hole H2 for attaching the insulator IS exists in the vehicle body panel BP, the outer claw 4 is configured to function as a means for engaging with the rear surface of the edge of the mounting hole H2. did. For this reason, the clip CP of this embodiment uses the stud bolt SB of the vehicle body panel BP to attach the insulator IS to the vehicle body panel BP, and the insulator CP using the attachment hole H2 of the vehicle body panel BP. It is possible to flexibly deal with both of the second mounting cases where the IS is mounted on the vehicle body panel BP. In this respect, the two types of clips having different mounting structures are integrated into one as described above. Therefore, it is suitable for facilitating mis-installation and inventory management due to clip misplacement.

In addition, according to the clip CP of the embodiment described above, the two types of clips are unified and unified as described above, so that only one mold is necessary for manufacturing the clip, thereby reducing the mold cost. Can also be planned.

The present invention is not limited to the embodiments described above, and many modifications can be made by those having ordinary knowledge in the art within the technical idea of the present invention.
