それがある。2. Description of the Related Art In recent years, the design stress of suspension coil springs has increased and the pitch angle has increased due to the practical use of high-strength spring steel and the improvement of processing techniques such as special shot peening in order to reduce the weight and size. As a result, lateral force acts even in the case of parallel compression that displaces the spring seat only in the direction of the coil axis, and when extrapolated to the shock absorber, the lateral force causes twisting between the absorber rod and the absorber tube, Riding comfort may be degraded and the life of the absorber may be shortened.

達成することができる。Means for Solving the Problems, Actions and Effects As means for solving the above-mentioned problems, the invention of claim 1 is directed to a circumferential direction of an insulator interposed between a lower sheet and the compression coil spring. Since the length can be adjusted, by adjusting the length of the portion of the compression coil spring that hits the insulator, the effective number of turns can be adjusted to an appropriate value and the lateral force acting on the compression coil spring can be reduced. This has the effect of improving ride comfort and extending the life of the shock absorber.
According to the invention of (1), the insulator is changed to one having a different circumferential length, and in the invention of claim (3), the number of insulators is changed in the invention of claim (1). By adjusting the length of the end turns of the coil spring, the effective number of turns can be set to an appropriate value, and the effect of the first aspect of the invention can be reliably achieved.
