Claims

[Scope of utility model registration request]

By separating the inside of the cylinder into two oil chambers by a piston fixed to the end of the piston rod, and allowing hydraulic oil to flow between the two oil chambers through the gap created between the piston and the cylinder when the piston rod is operated. In the shock absorber configured to generate a damping force, the piston rod includes a guide piston whose outer periphery slides on the inner circumferential wall of the cylinder and which has oil holes that open and communicate with each other on both end surfaces, and is arranged in parallel with the piston. A shock absorber featuring:
