BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a trim fixing clip according to a preferred embodiment of the present invention; FIG. Although it is provided with the member 1 and the second member 11, unlike the conventional case, the two members 1 and 11 are formed into a one-piece type integrally through a thin connecting piece 21.

Therefore, the members 1 and 11 will be described in detail. First, as shown in FIGS. 3A and 3B, the first member 1 has a hollow cylindrical portion 2 into which a stud bolt provided on the panel side is inserted. And a pair of flanges 3 each having a disk-shaped flange portion 3 having a diameter larger than the mounting hole provided on the trim side, and projecting inward from the opposite side surface of the hollow cylindrical portion 2 to engage with the threaded surface of the stud bolt. Are formed through the window 5 and an annular groove 6 is formed on the outer peripheral surface of the distal end of the hollow cylindrical portion 2.

As shown in FIGS. 3A and 3C, the second member 11 includes an annular base 12 having a diameter larger than a mounting hole provided on the trim side, similarly to the flange 3 described above. 1
2 has an annular wall 14 that is slightly smaller than that of the first member 1, and has a fitting hole 15 for fitting the hollow cylindrical portion 2 of the first member 1 inside the annular wall 14. At the same time, four elastic pieces 16 are provided at equal intervals on the opening edge of the annular wall 14, and are provided on the outer surface of each elastic piece 16 so as to engage with the peripheral surface of the mounting hole of the trim. The pawl 17 is formed integrally, and a projection 18 is formed integrally on the inner surface of each of the elastic pieces 16 so as to come into contact with the annular groove 6 formed on the outer peripheral surface of the distal end of the hollow cylindrical portion 2. In addition, each of the projections 18
Is set to be smaller than the groove diameter of the annular groove 6 of the first member 1.

Therefore, when the trim T is fixed to the panel P using the clip and the stud bolt B having such a configuration, first, each elastic piece 16 of the second member 11 is attached to the mounting hole H of the trim T. A state in which the hollow cylindrical portion 2 of the first member 1 is inserted into the insertion hole 15 of the second member 11
As shown in FIG. 4, the projections 18 formed on the inner surfaces of the respective elastic pieces 16 are fitted and abutted on the annular grooves 6 of the hollow cylindrical portion 2 to forcibly remove the respective elastic pieces 16. As a result, the engaging claw 17 formed on the outer surface of each elastic piece 16 can be firmly engaged with the peripheral surface of the mounting hole H. Tentatively assuredly.

Therefore, even if an unexpected external force or the like is applied, each elastic piece 16 never bends inward due to the fitting abutment of the projection 18 against the annular groove 6, so that the clip is trimmed. That is, there is no need to worry about the attachment hole H of the T coming off. In this case, the edge of the mounting hole H of the trim T is aligned with each of the locking claws 17 and the annular base 12.
As a result, the temporary holding state of the clip is strengthened, and the annular base 12 of the second member 11 comes into close contact with the surface of the trim T, thereby fixing the trim T. It will also contribute to the sound insulation effect later.

Therefore, after that, in such a temporary holding state,
When the tip of the stud bolt B is inserted into the hollow cylindrical portion 2 while the hollow cylindrical portion 2 of the first member 1 is facing above the stud bolt B, a pair of engaging members formed in the hollow cylindrical portion 2 are formed. Since the stop piece 4 is elastically locked to the corresponding screw surface of the stud bolt B, this causes the
At the same time when the clip itself is fixed to the stud bolt B, the trim T is fixed to the panel P side.

In addition to closing with the flange 3 of the first member 1 in cooperation with the annular base 12 of the first member 1, the flange 3 of the first member 1 and the annular base 12 of the second member 11 are in close contact with each other, and Since the hollow cylindrical portion 2 of the one member 1 and the annular wall 14 of the second member 11 are in close contact with each other and a double close sealing state is obtained, a reliable sound insulation effect can be expected. In this case, as shown in FIG. 6, if the space formed between the annular base 12 and the annular wall 14 of the second member 11 is entirely covered with the continuous support wall 13, the sound insulation effect is further ensured. .

In the fixed state of the trim T, the first member 1 is strongly pressed against the panel P so as to sandwich the second member 11 and the trim T. Annular base 12 of member 11 and annular base 12
And the surface of the trim T are sufficiently adhered to each other, so that unnecessary rattling can be suppressed and the sound insulation effect can be improved. In this case, it is more effective if the length of the portion of the first member 1 inserted into the mounting hole H of the hollow cylindrical portion 2 is set to be smaller than the thickness of the trim T. is there.

Further, although not specifically shown, the trim T
If it becomes necessary to remove the panel from the panel P,
Operation rib 7 provided on flange 3 of first member 1
When the first member 1 is rotated in a predetermined direction together with the second member 11 by using the above, the trim T can be easily removed from the panel P with the clip attached to the mounting hole H of the trim T. .

In the present embodiment, the one-piece molding of the first member 1 and the second member 11 via the thin connecting piece 21 makes the handling of the clip itself extremely convenient and This will greatly contribute to lowering the die cost.
