とを特徴とする油圧緩衝器。 A check valve that allows hydraulic oil to flow in from an external reservoir chamber is disposed in the lower oil chamber in the cylinder, which is divided into upper and lower sections by a piston with a damping valve, and a check valve that allows hydraulic oil to flow in from an external reservoir chamber is disposed between the upper oil chamber and the reservoir chamber. In a hydraulic shock absorbing mechanism, an annular valve is movably fitted under the action of sliding resistance in the upper part of the cylinder of a piston rod that enters from the upper end of the cylinder, and A hydraulic shock absorber characterized in that the oil passage is formed by opening a through hole communicating with an external reservoir chamber at a position of the inner wall of the cylinder that comes into contact with the upward movement of the valve.
