緩衝器。 A piston rod is movably inserted into the cylinder via a piston, and the piston defines two oil chambers within the cylinder, and these two oil chambers communicate with each other via an extension port and a pressure port provided on the piston. In the hydraulic shock absorber, the expansion port and the pressure port are provided with disc valves that can be opened and closed, respectively, and both disc valves are held by a nut screwed onto the piston rod via a valve spring and a spring plate. an inner diameter portion of the piston that accommodates the spring plate;
A hydraulic shock absorber characterized in that a plurality of protrusions are provided for concentrically positioning the outer diameter of the spring plate.
