VEHICLE HEIGHT ADJUSTMENT DEVICE AND VEHICLE HEIGHT ADJUSTMENT METHOD

摘要

A vehicle height adjustment device has an adjustment bolt (30) rotatably supported by or fixed to a wheel side member or a vehicle body member, and has a spring member (10) screwed on to the adjustment bolt. The rotation of the spring sheet member is limited by a bump rubber seat (41) (or a coil spring bracket (9)). The spring sheet member is displaced relative to the rotation axis direction of the adjustment bolt as the adjustment bolt rotates. The rotation of the spring sheet involved in the rotation of the vehicle height adjustment bolt is restricted, and the structure of a vehicle height adjustment mechanism is simplified to enable the reduction in the number of parts or members of the vehicle height adjustment device.
