のピストン。In a piston of a hydraulic shock absorber, in which a ring groove into which a piston ring is fitted is formed on the outer periphery of a piston body that is slidably inserted into a cylinder, a radius of the bottom portion is formed at the bottom of the ring groove. A piston ring is formed of a resin or the like that elastically contracts when the diameter is expanded and installed in the ring groove, and the piston ring contracts at the bottom of the ring groove. A piston of a hydraulic shock absorber, which is fastened with a diameter and whose inner circumferential surface bites into the stepped portion.
