る減衰力可変型液圧緩衝器。 The piston includes a cylinder filled with hydraulic fluid, and a piston that divides the inside of the cylinder into two chambers, is slidably fitted into the inner wall of the cylinder, and has an orifice that communicates the two chambers, and the cross-sectional area of the orifice is In a variable damping force hydraulic shock absorber, the damping force can be varied by changing the flow resistance of the hydraulic fluid, and a piezoelectric element is provided to open and close the orifice, and the cross-sectional area of the orifice can be changed by changing the voltage applied to the piezoelectric element. A variable damping force type hydraulic shock absorber characterized in that the damping force is continuously changed.
