とを特徴とする減衰力調整装置。 A damping force formed by disposing expansion-side and compression-side damping valves on the end face of a valve seat member and adjusting the height of the expansion-side and compression-side damping forces generated by the damping valves. In the adjustment device, each of the damping valves on the expansion side and compression side has an electrostrictive body made of an annular piezoelectric material integrally attached to the back pressure surface of a valve body made of an annular leaf valve, and the electrostrictive body is provided with the same pressure from the controller. It is formed to exhibit a predetermined electrostrictive effect when voltages of polarity and reverse polarity are applied, and it is formed so that the detected value from the speed sensor that detects the piston speed is input to the controller. A damping force adjusting device characterized by:
