バ。[Claims for Utility Model Registration] A tube connected to one member; and a tube connected to the other member and slidably disposed within the tube, and a first oil chamber and a second oil chamber connected to the other member.
A variable damping force shock absorber comprising: a piston partitioned into an oil chamber; a valve that changes the communication area of a communication passage that communicates the first oil chamber and the second oil chamber; and an actuator that displaces the valve. , the actuator includes (a) an amplification means for increasing the output displacement amount of the piezoelectric element that expands and contracts in response to an applied voltage and transmits it to the valve; a large-diameter piston that is driven by an output and moves; (a-2) the large-diameter piston is slidably arranged;
a cylinder whose internal oil pressure changes according to the amount of movement of the large diameter piston; (a-3) a plunger having a smaller diameter than the large diameter piston that is driven by the oil pressure in the cylinder and moves; (b) a disc spring for applying an initial load to the piezoelectric element is disposed in a hydraulic expansion chamber surrounded by the large-diameter piston and the cylinder; A variable damping force shock absorber, characterized in that said hydraulic expansion chamber is communicated with each other by a communication means.
