Claims

[Scope of Claim for Utility Model Registration] An actuator that is interposed between a vehicle body and each wheel and that can change the vehicle height by operating in response to control fluid pressure introduced from a fluid pressure control circuit; , a hydraulic sealing means formed to be able to confine hydraulic pressure within the actuator; a communication path connecting the pair of left and right actuators so that the hydraulic fluid in the internal liquid chamber can flow therethrough; and a communication path in the middle of the communication path. A first valve is provided, which is normally closed to block the communication passage, and which is opened to bring the communication passage into a communication state when the hydraulic pressure sealing means is in a sealing operation.
a cut valve; and a second cut valve connected to the communication passage so as to communicate with the communication passage in conjunction with opening of the first cut valve, and to relieve hydraulic pressure in the communication passage at a predetermined hydraulic pressure or higher. A suspension device for a vehicle, comprising: a relief circuit provided with a relief valve that opens;
