Claims

[Claims for Utility Model Registration] (1) The product is formed so as to be able to supply high-pressure hydraulic oil from a hydraulic source to suspension cylinders disposed at each of the four wheels of a vehicle through an active control valve. , in a suspension device configured to discharge hydraulic oil from the suspension cylinder to a tank via the active control valve, a supply oil that enables communication between the hydraulic pressure source and the active control valve; A holding valve is disposed in the discharge oil passage that allows communication between the active control valve and the tank and allows selective flow of hydraulic oil in each oil passage. A suspension device characterized by: (2) The suspension device according to claim 1, wherein the holding valve is configured to be switched to the communicating position by energizing a solenoid. (3) The suspension device according to claim 1, wherein the holding valve is configured to be switched to the communication position by supplying pilot pressure. (4) The suspension device according to claim 1, wherein a sub-accumulator is attached to the suspension cylinder via a damping valve.
