Claims

[Claims for Utility Model Registration] A piston is slidably inserted into a cylinder filled with oil to define two chambers, and the pre-produced piston is extended to the outside of the cylinder. a piston rod and a bottomed cylindrical fixing member having an open end facing the piston, the piston rod being removably fixed and held between the piston rod and the piston rod, a cavity extending in the axial direction of the piston rod being formed in the piston rod, and the cavity being connected to the piston rod; an inner end surface of the piston rod opens into one of the two chambers and communicates the cavity with the other of the two chambers, and a metering pin is inserted into the cavity against the bottom of the fixture. In a hydraulic shock absorber, the metering pin is passed through with a loose fit, and the outer diameter of the metering pin is larger on the side in the direction of contraction of the piston rod than on the side in the direction of extension of the piston rod. a space is formed between the inner bottom of the fixture, a valve body is provided in the inner bottom of the fixture so that it can be placed in and out of the way, and the valve body cooperates with the fixture so that the valve body A hydraulic shock absorber, characterized in that when separated from the inner bottom of the fixture, a communication path is formed that communicates the cavity and the one chamber.
