ていることを特徴とする車高調整装置。[Scope of Claim for Utility Model Registration] An accumulator that temporarily stores hydraulic pressure supplied from a pump, a first check valve on the supply side to prevent backflow provided between the accumulator and the pump, and a hydraulic pressure supplied to the accumulator. A pressure control valve that is connected via the supply circuit and the drain circuit to control output hydraulic pressure; and a vehicle height adjustment actuator that is driven by the output hydraulic pressure of the pressure control valve and controls vehicle height and attitude. and a second supply side check valve, which is provided between the accumulator and the pressure control valve of the hydraulic pressure supply circuit, and which regulates the movement of hydraulic pressure toward the pressure control valve in a closed state; and a second supply side check valve, which is provided in the drain circuit, and which prevents backflow. and a drain side check valve, wherein the second supply side check valve and the drain side check valve each use the hydraulic pressure of the accumulator as a pilot pressure, and the hydraulic pressure of the accumulator controls the vehicle at the vehicle height adjustment actuator. A vehicle height adjustment device characterized in that the device is configured to open when the hydraulic pressure is higher than a set hydraulic pressure that sets a predetermined vehicle height, and close when the hydraulic pressure is lower than the set hydraulic pressure.
