い。 However, because the seat surface of the suspension arm is inclined as described above and the winding start end of the coil spring protrudes in the axial direction of the coil spring, the installation position of the winding start end with respect to the seat surface is difficult. In some cases, the coil spring comes into contact with the insulator only at a small length including the winding start end, and when the coil spring is lifted by a lifter, the coil spring rotates around the small contact area. The product may fall over and become almost detached from the insulator. To avoid that,
The worker is lifting the coil spring with a lifter while supporting the coil spring with his/her hands, which is not favorable for the work.

の間隔が定められる。 The insulator 10 is made of rubber and prevents vibrations applied to the suspension arm 12 from being transmitted to the vehicle body via the coil spring 16. The insulator 10 includes a cylindrical portion 22 that is fitted into a convex portion 15 of a seat surface 14 of a suspension arm, and a generally annular seat portion 2 that extends radially outward from the cylindrical portion 22.
3 and a flange portion 24. Seat part 23
A locking portion 25 for receiving the winding start end 17 of the coil spring 16 is provided, and the flange portion 24 is provided in the vicinity of the outer periphery of the seat portion 23, including a portion facing the locking portion 25, and extends upwardly. It is growing to. The height and distance of the flange portion 24 from the cylindrical portion 22 are determined such that the winding start portion of the coil spring 16 placed on the seat portion 23 comes into contact with the flange portion 24 .

As shown in the figure, the suspension arm 12 hangs down due to its own weight. In this state, move the insulator 10 to the seat surface 1 of the suspension arm.
4, and the coil spring 16 is placed thereon so that the winding start end 17 of the coil spring 16 is received by the locking part 25 of the seat part 23 of the insulator. In this state, the coil spring 16 is in contact with the insulator 10 at the winding start end 17 and the winding start part in the vicinity, and the rest is floating from the insulator 10, but the winding start part of the coil spring 16 that contacts the insulator is in contact with the insulator 10. As shown in the figure, since the coil spring 16 is also in contact with the flange portion 24 of the insulator, and the frictional force of the flange portion 24 acts on the coil spring 16, the coil spring 16 is prevented from falling down due to rotation. As a result, the suspension arm 12 is raised using the lifter, and the coil spring 16
The upper end of the can be guided to a predetermined position on the vehicle body.
