Claims

[Claims for Utility Model Registration] (1) A first member and a second member that move relative to each other in the axial direction, and a resin band that is press-fitted into the first member and comes into sliding contact with the second member. A hydraulic shock absorber comprising: both axial ends of the resin band are caulked to the first member, and one end is attached to the first member at a contact surface between the first member and the resin band. A hydraulic shock absorber characterized in that a back pressure passage is formed, the other end of which communicates with the hydraulic chamber. (2) The hydraulic shock absorber according to claim 1, wherein the first member is a piston and the second member is a cylinder. (3) The hydraulic shock absorber according to claim 1, wherein the first member is a guide for a piston rod, and the second member is a piston rod.
