い。However, in the conventional vehicle height adjusting device of the vehicle, the damper is supported by the vehicle body side mount, but the coil spring and the bump stopper are rotated by the bearing supported by the vehicle body. Since the reaction force is applied to the member, when the suspension strokes and the coil spring and the bump stopper generate a reaction force, all the reaction force is input to the bearing via the rotating member. Therefore, it is necessary to increase the withstand load of the bearing, and as a result, it is necessary to use a bearing with a high withstand load, which tends to increase the weight and increase the cost.
