第１項記載の油圧緩衝器。[Claims for Utility Model Registration] (1) Hydraulic buffer formed so that the deflection characteristics of the leaf valve can be changed by the internal pressure in the first-order lag pressure chamber that communicates with the cylinder oil chamber via an orifice. In the pressure chamber, the lower end of a rod body formed so as to be approached by operating the actuator faces the orifice, and the lower end of the rod body adjusts the amount of oil flowing into the pressure chamber through the orifice. A hydraulic shock absorber characterized in that it is formed to. (2) The hydraulic shock absorber according to claim 1, wherein the orifice is formed in the center of a plate member defining a pressure chamber. (3) The hydraulic shock absorber according to claim 1, wherein the actuator is made of a piezoelectric element and is housed in a piston rod. (4) The hydraulic shock absorber according to claim 1, wherein the rod body is housed within the piston rod. (5) The hydraulic shock absorber according to claim 1, wherein the pressure chamber is formed in a piston nut that fixes the piston body of the piston portion to the lower end of the piston rod. (6) The hydraulic shock absorber according to claim 1, wherein the leaf valve is housed in a piston nut that fixes the piston body of the piston portion to the lower end of the piston rod.
