の範囲第１項記載の油圧緩衝器。[Claims for Utility Model Registration] (1) The cylinder is formed so that the hydraulic oil in the upper chamber in the cylinder flows into the lower chamber in the cylinder only through a rotary valve disposed in the passage in the piston rod. Leaf valves with different thicknesses are arranged in the inner piston part in multiple stages to enable generation of rebound damping force, and the hydraulic oil can pass through any one or more of the multi-stage leaf valves. A hydraulic shock absorber characterized in that it is formed as follows. (2) The hydraulic shock absorber according to claim 1, wherein each leaf valve is arranged adjacent to the lower surface of a seat member formed separately from the piston body in the piston portion. (3) The hydraulic shock absorber according to claim 1, wherein the leaf valves are arranged in two stages, upper and lower, in the piston portion.
