摘要： PURPOSE: To smoothly slide a piston by arranging a hydraulic cylinder in a wheel supporting member movable axially and rotatably provided on a guiding casing, and closing it by a piston fixedly combined with the guiding casing so as to form a pressure chamber. CONSTITUTION: A cylindrical supporting member 4 movable axially and rotatably relative to it is arranged in a guiding casing 3 fixed to a vehicle chassis 1, and it is combined with the supporting body 7 of a wheel through a flange 6. A piston 11 is arranged in the supporting member 4, and the piston rod 12 is extendingly provided in the apart direction from the flange 6, to be fixed with the bottom part 13 of the guiding casing 3. The cylinder chamber between the flange 6 and the piston 11 is formed in a hydraulic cylinder 10, a closed pressure chamber 14 of the hydraulic cylinder shock absorber, and it is connected to an accumulator 17 through a hole 15 and a conduit 16. By this constitution, hydraulic pressure exists only in the supporting member to eliminate oil leak, and the piston can be smoothly slided.
