環状の金属製カラー８を係着させたものである。1 is a longitudinal sectional view showing an embodiment of a grommet fixing structure according to the present invention, and FIG. 2 is an enlarged view of a portion A thereof. This structure has a substantially cylindrical elastic (rubber) grommet 1.
A metal reinforcing plate 4 is provided inside a flange portion 3 integrally formed with the tip end side (connector accommodating portion) 2 of the vehicle, and the reinforcing plate 4 is installed in a bolt hole 5 of the flange portion 3 in a vehicle panel. 6 is bent to form the guide portion 7, and the bolt hole 5 along the guide portion 7 is shorter than the plate thickness T of the flange portion 3 (L).
An annular metal collar 8 is attached.

してある。A diameter-increased opening 9 is formed outside the guide portion 7, and annular collar portions 10 and 11 which are folded back toward the outside are formed at both ends of the collar 8, respectively. One flange 10 is placed on the edge 12 on the bolt insertion side, and the other flange 1 on the panel 6 side in the opening 9 is formed.
1 can be moved in the direction in which the bolt 13 is screwed in (the direction of arrow A).

る。FIG. 3 shows a state in which the bolt 13 is screwed into the fixing nut 18 of the vehicle panel 6 and the flange portion 3 is tightened and fixed. That is, as shown in FIG. 2, the collar 8 having the flange portion 10 protruding from the surface of the flange portion 3 is pressed by the washer 19 of the bolt 13 so that the collar portion 10 is pressed and is embedded in the flange rubber 3a. The washer 19 is displaced in the insertion direction (the direction of arrow A), and the washer 19 is inserted through the rubber 3a.
The pressing force of (3) is received by the internal reinforcing plate 4 and the amount of compression of the flange portion 3 that is wholly compressed is regulated so that it is not compressed below the length L (see FIG. 2) of the collar 8.

錆を生じることもない。Here, since the collar 8 is formed in an annular shape, it has excellent strength in the compression direction, and reliably receives the tightening force of the bolt 13. Therefore, the bolt 13 is not overtightened, and the flange rubber 3a is not damaged. Furthermore, since the metal reinforcing plate 4 is disposed inside the flange,
It does not cause rust.

Indicates a vehicle panel, and 1 indicates the above-mentioned grommet, and one connector 21 is housed in the grommet 1 without backlash. That is, the ribs 22 projecting inside the housing portion 2
The connector 21 is held in the grommet 1 without backlash by slidingly contacting the outer wall surface of the connector 21 to accommodate the connector 21.

業を容易に行うことができる。By fitting the connector 21 into the fixed connector 23 mounted on the vehicle panel 6 side, the bolt holes 5 of the flange portion 3 of the grommet 1 are simultaneously aligned with the fixed nut 24 of the vehicle panel 6. Further, since the flange portion 3 is not displaced even when the grommet 1 is released from the hand, the bolt 13 can be easily screwed in.

ル性を付与させる。When the bolt 13 is tightened, as described above, the collar 8 in the bolt hole 5 reliably receives the tightening force to provide a moderation of tightening, and the flange portion 3 (reinforcement due to over tightening). The plate 4) is prevented from being deformed and a good sealing property is given.
