By supplying pressure oil from a hydraulic unit to the suspension body provided between the vehicle body and each axle to extend it, or by discharging pressure oil from the suspension body and returning it to the hydraulic unit, it contracts. A hydraulic suspension device adapted to adjust vehicle height, comprising: a flow rate adjustment valve provided in a hydraulic conduit between the suspension body and the hydraulic unit; and a sensor for detecting pressure within the suspension body; It is composed of a sensor that detects the vehicle height, and a control circuit that operates the flow rate adjustment valve based on the detection data of these pressure sensors and the vehicle height sensor. A control operation that increases fluid resistance by operating the flow rate adjustment valve when pressure oil is supplied to the suspension body under conditions lower than the pressure setting value, and a control operation that increases fluid resistance when the hydraulic pressure inside the suspension body is higher than the pressure setting value. A hydraulic suspension device characterized in that a control operation is performed to increase fluid resistance by operating the flow rate regulating valve when pressure oil is discharged from the main body.
