ツクアブソーバのピストン部構造。[Claims for Utility Model Registration] (1) A shock absorber that is slidably inserted into a cylinder and is formed so as to press and hold a resin bearing member facing the inner peripheral surface of the cylinder on its outer periphery. In the piston part structure, the bearing member has a cylindrical main body part that is crimped and held on the outer peripheral surface of the piston main body, and has a lip part integrally formed at one end of the cylindrical main body part, A structure of a piston portion of a shock absorber, characterized in that the piston portion structure is formed so that an outer peripheral edge of the piston portion can come into sliding contact with an inner peripheral surface of a cylinder. (2) The bearing member is made of a long extruded pipe-shaped material made of a thermoplastic fluororesin such as tetrafluoroethylene/perfluoroargooxyethylene copolymer or tetrafluoroethylene/ethylene copolymer, and is made into appropriate dimensions. A piston portion structure of a shock absorber according to claim 1, which is formed by cutting. (3) The shock according to claim 1 of the utility model registration, wherein the bearing member is formed such that the lip portion is press-formed when the cylindrical body is pressed and held on the outer peripheral surface of the piston body. Absorber piston structure. (4) The scope of the utility model registration claim, which is formed so that when the piston part slides inside the cylinder, hydraulic pressure in the cylinder acts on the inner peripheral side of the lip part, and the outer peripheral edge of the lip part is pressed against the inner peripheral surface of the cylinder. A structure of a piston portion of a shock absorber according to item 1.
