As shown in, the stud bolt B is erected on the panel P side,
A mounting hole 32 with a cutout for mounting the vibration absorber 33 is opened on the component 31 side, while the vibration absorber 33 is formed into a cylindrical body, and a metal collar 36 is fitted inside the vibration absorber 33.

First, as described above, when the pair of rotation preventing pieces 8 are located in the longitudinal direction of the mounting hole H and the lower end side of the sleeve body 1 is inserted into the mounting hole H of the component P1, the pair of rotation preventing pieces 8 rotate. The prevention piece 8 passes through the inside of the mounting hole H without receiving any resistance, but the pair of lower elastic pieces 7 passes through the mounting hole H while being pushed inward by the edge of the mounting hole H, and passes completely. At the same time, each tip edge of the pair of upper elastic pieces 6 makes elastic contact with the upper peripheral surface of the mounting hole H of the component P1, and at the same time, each tip edge of the pair of lower elastic piece 7 is attached to the lower peripheral surface of the same mounting hole H. Then, as shown in FIG. 3, the peripheral surface of the mounting hole H is elastically held from above and below.

とが好ましい。Therefore, under the first embodiment, as compared with the conventional anti-vibration fixing structure, the work of fixing the component P1 to the panel P2 becomes easy while significantly reducing the number of used members. In addition to the advantage, when the vertical vibration is applied in the fixed state, it is effectively absorbed by the elastic action of the upper elastic piece 6 and the lower elastic piece 7 which are in a vertical pair relationship. In the case where the opposite lateral vibration is applied, it can be effectively absorbed by the elastic deformation of the elastic locking claws 2 locked to the threaded surface of the stud bolt B. However, it is possible to prevent the mechanical vibration generated on the component P1 side or the panel P2 side from being transmitted to the other side. In particular, in order to enhance the vibration damping effect in the lateral direction, it is preferable to set the size of each elastic locking claw 2 as long as possible.

る。In addition, in the second embodiment, when lateral vibration is applied, in addition to the elastic deformation of the elastic locking claw 2 which is locked to the thread surface of the stud bolt B, an annular shape is formed. Even when the void portion 14 is deformed, the vibration can be effectively absorbed, so that a very rational vibration damping effect can be expected. Therefore, the annular void portion 14 has a certain meaning of existence, but it does not always have to exist under the present invention. If the annular void 14 is not formed, the elastic body 10 may be attached to the mounting hole H on the component P1 side alone, and the sleeve body 1 may be fitted into the elastic body 10 later. As a result, a mounting state similar to the above with respect to the component P1 side can be obtained.

こととなる。As described above, the anti-vibration clip according to the present invention is different from the conventional anti-vibration fixing structure by adopting the above-mentioned structure, and while fixing the parts to the panel while reducing the number of used members. It has become possible to greatly simplify. In addition, the elastic action of the upper and lower elastic pieces, which are the vibration absorbing means, on the peripheral surface of the mounting hole of the component and the elastic contact action of the elastic member on the hole edge of the mounting hole of the component cause mechanical damage on the component side or panel side. Since it is possible to effectively prevent the vibration from being transmitted to the other, it is possible to expect an improvement in the vibration damping effect. Further, the mounting hole formed on the component side is not limited to the conventional one having a cutout, so that the rigidity of the component itself can be increased and the range of use thereof can be expected to be expanded.
