A fluid actuator for driving a leveling valve that drives a leveling valve that controls oil supply/drainage of the front wheel side hydropneumatic suspension in response to a change in vehicle height and the brake-linked fluid cylinder are in communication with each other. For a vehicle, characterized in that a communication oil passage communicating between the left and right hydro-pneumatic suspensions on the front wheel side is provided with an opening/closing valve that opens and closes the communication oil passage in response to the steering interlocking cylinder. Hydraulic pneumatic suspension device.
