とする減衰力可変型液圧緩衝器。 A cylinder filled with hydraulic fluid, a rebound liquid chamber that is provided at the tip of a piston rod inserted from one end of the cylinder, and whose volume decreases during the rebound stroke of the hydraulic shock absorber inside the cylinder, and its volume during the pressure side stroke. A piston defined in the pressure side liquid chamber to be reduced, a flow path communicating the expansion side liquid chamber and the pressure side liquid chamber via a hollow part provided in the piston, and a piston that slides into the hollow part in the piston. It is freely inserted and defines the hollow part into a liquid chamber communicating with the expansion side liquid chamber and a liquid chamber communicating with the compression side liquid chamber, and is provided with an expansion side passage and a compression side passage that separately communicate the two chambers. A valve body, a compression side disk valve and a compression side disk valve, which are arranged on both sides of the valve body and close the expansion side passage or the compression side passage according to their bending rigidity, and generate a damping force according to the bending rigidity, and the expansion side disk. The first and second piezoelectric elements are disposed on the opposite side from the valve and the pressure-side disc valve, and change the bending rigidity of the disc valve by pressing both the disc valves against the valve body. A variable damping force hydraulic shock absorber.
