PURPOSE:To restrain the attitude change of a car, with a suspension bush into which pressurized fluid can be poured, on acceleration by making the caster angle of the car smaller by means of controlling the pouring of pressurized fluid so as to shift the fixing center of the suspension bush frontward. CONSTITUTION:A suspension bush (UPPER SUPPORT) 1, which is used at the joint of a shock absorber upper end and a car body, has a ring-shaped elastic member between the outer and inner members and, in this elastic member, hollow bodies 6a and 6b are formed before and behind the fixing center of this push 1. In this case, each of the hollow bodies 6a and 6b can be connected to an oil pump 14 or a fluid reservoir 15 via a pressure control valve 10 consisting of electromagnetic direction switch valves 11 and 17, and electromagnetic open/ close valves 12 and 18. And, when the car speed is accelerated, the fixing center of the bush 1 is shifted frontward to reduce the caster angle of the car by pouring fluid into the rear hollow body 6b and taking fluid out of the front hollow body 6a. |
