As is well known, the shock absorber 10 is one of the main components of a suspension system for a vehicle, and is mounted between a vehicle body 20 and a wheel with a suspension arm 18, 19 interposed between the vehicle body 20 and the wheel to brake against shaking of the vehicle. It acts as a resistance.

The base 11 is integrally mounted and fixed to the outer circumferential surface of the shock absorber 10, and a male spiral is formed on the outer circumferential surface thereof.

The spring seat 12 supports the suspension gas spring 16 disposed outside the shock absorber 10, and is fixed to the outer circumferential surface of the shock absorber 10 at an upper portion of the base 11 so that the suspension gas spring 16 is fixed. Supporting the lower end of the, and has a spiral structure according to the lower shape of the suspension gas spring 16 to support the lower end of the suspension gas spring (16).

The length adjusting member 13 is formed with a spiral corresponding to the male spiral shape of the base 11 on the inner circumferential surface, and is assembled to be linearly movable in the longitudinal direction of the shock absorber 10 on the outer circumferential surface of the base 11.

The length adjusting member 13 is for adjusting the vertical height of the vehicle by adjusting the vertical length of the shock absorber 10 by expanding or compressing the shock absorber 10 as it is rotated by an operator's operation. 11) is assembled to the outer circumferential surface of the spiral seat is located in the lower portion of the spring seat 12 and the current gas spring (16).

When the length adjusting member 13 is rotated in the direction in which the suspension gas spring 16 is compressed in order to adjust the height of the vehicle, the load applied to the suspension gas spring 16 is constant, so that the suspension gas spring 16 is moved up and down. The length is kept constant, the length adjusting member 13 is fixed to the lower portion of the current gas spring 16 without moving in the longitudinal direction of the shock absorber 10 on the base (11).

Therefore, when the operator rotates the length adjusting member 13 in one direction to compress the current gas spring 16, the length adjusting member 13 does not linearly move in the longitudinal direction of the shock absorber 10, but the shock absorber 10 ) Is extended to change the height of the vehicle.

In other words, when adjusting the height of the vehicle by rotating the length adjusting member 13 in one direction, the shock absorber 10 is fixed as the length adjusting member 13 is positioned below the current gas spring 16. It extends in the axial direction.

In addition, the length adjusting member 13 is provided with a rotation preventing member 14 for preventing rotation of the length adjusting member 13 while traveling.
