To provide a compact and lightweight hydraulic control device in an active suspension that does not require a hydraulic pump and a complex tubular hydraulic piping.SOLUTION: An active suspension device for vehicle that controls the vehicle height or cushioning force, includes: a coupling cover that separates an accumulator and connects a shock absorber and the actuator; an accumulator communication pipe that connects the accumulator to a solenoid valve; a shock absorber communication pipe that connects the shock absorber to the solenoid valve in both forward and reverse directions via a check valve; an actuator communication pipe that connects the actuator to the solenoid valve; and the solenoid valve that controls opening/closing of each communication pipe. The active suspension device for vehicle controls the solenoid valve to control the vehicle height or cushioning force of each axle, and forms a valve section of the solenoid valve inside the coupling cover.SELECTED DRAWING: Figure 1
