とする油圧緩衝器。(1) A cylinder, and a piston ront with one end located within the cylinder and the other end protruding outside the cylinder;
a piston inserted into the piston rod so as to be displaceable in the axial direction; an oil passage bored in the piston and communicating two chambers defined in the cylinder by the piston; and the piston rod. a retainer fixed to the
A disc valve is interposed between the retainer and the piston and has a notched groove formed on the outer peripheral side, and the piston has an annular protrusion that comes into contact with the outer peripheral edge of the disc valve when the piston is displaced. The retainer is formed with an annular protrusion on the inner circumferential side that serves as a bending fulcrum when the disc valve is pushed by the annular protrusion of the piston, and an annular protrusion on the outer circumferential side that serves as a bending point when the disc valve is pushed by the annular protrusion of the piston. In the hydraulic shock absorber, an annular projection is formed between which the outer circumferential portion of the disc valve is held. A hydraulic shock absorber characterized in that each of the annular protrusions is configured such that the overlapping portion between the annular protrusion and the contact surface is reduced.
