る減衰力調整装置。 The expansion-side leaf valve, which is a damping valve on the rebound side, and the compression-side leaf valve, which is a damping valve on the compression side, are respectively disposed on the lower and upper end surfaces of the piston body that slides within the cylinder. It is formed so that back pressure acts on it through the sub-valve, and when a voltage is applied to the piezoelectric element, which is an electrostrictive member, which is disposed in the piston rod inserted into the cylinder, the amount of deflection of the circumferential end of each leaf valve, which is a damping valve, is calculated. The sub-valves on each side are arranged in a tip spigot member connected to the tip of the piston rod, and are connected to the electrostrictive member. In a damping force adjustment device that is formed so that the amount of peripheral deflection is changed by the expansion force generated when a voltage is applied, a push rod and a valve disk are provided in the tip pilot member so as to be movable up and down, and the valve disk is moved up and down. A compression side sub-valve and an expansion side sub-valve are provided at the end, and a passage for applying pressure oil to each side sub-valve is formed.The push rod contacts the compression side sub-valve and is interlocked with the electrostrictive member, so that the movement of the push rod is applied to the valve disc. A damping force adjusting device characterized in that the damping force is transmitted.
