Claims

[Scope of utility model registration request]

A hydraulic shock absorber comprising a hydraulic shock absorber main body having an engaging protrusion protruding from the outer circumferential side, and a piston rod projecting from the hydraulic shock absorber main body so as to be extendable and retractable in the axial direction, in which the piston rod is biased toward the extension side. A spring seat whose inner circumferential side is engaged with the engagement protrusion of the hydraulic shock absorber main body in order to support one end side of the spring, and a spring seat between the inner circumferential side of the spring seat and the outer circumferential side of the hydraulic shock absorber main body. A hydraulic shock absorber characterized by comprising an interposed elastic member.
