る車高調整装置。 A suspension device that is interposed between the wheels and the vehicle body and has an air chamber that expands and contracts to cause relative displacement between the wheels and the vehicle body, and a solenoid valve for supply and exhaust that opens and closes the air chamber of this suspension device. A pressure supply source that supplies compressed air to the air chamber through an installed pipe, a vehicle height sensor that outputs a detection signal according to the amount of relative displacement between the wheels and the vehicle body, a solenoid valve for supply and discharge, and a pressure An exhaust solenoid valve is disposed in a branch conduit branching from a conduit between supply sources and releases high-pressure air in the conduit to the atmosphere; A pressure sensor that turns on and outputs a detection signal when the internal pressure of the pipe exceeds a predetermined pressure when the vehicle height increases, and an exhaust solenoid valve that controls opening and closing based on input signals from the vehicle height sensor and pressure sensor. A vehicle height adjustment device comprising a controller that outputs a control signal.
