車高を調節することを特徴とする車高調整装置。A pressure fluid generation source that generates fluid at a predetermined pressure, a fluid chamber that can be expanded and contracted between the vehicle body and the wheel support member, a supply path that connects the pressure air generation source and the fluid chamber, and a supply path. A plurality of supply valves are provided in parallel in the supply chamber to open and close the supply path, and a plurality of supply valves are provided in series in the supply chamber to control the fluid pressure generated by the pressure fluid generation source to a predetermined pressure. A plurality of supply check valves that reduce pressure, a discharge passage that communicates the fluid chamber with the outside world, one or a plurality of discharge valves arranged in parallel provided in the discharge passage to open and close the discharge passage, and a plurality of discharge valves disposed in the discharge passage that open and close the discharge passage. one or more discharge check valves that are arranged in series with each discharge valve to reduce the internal pressure of the fluid chamber to a predetermined value; the plurality of supply valves and the one or more stroke discharge valves; 1. A vehicle height adjustment device, comprising: a switch means that is operated in a controlled manner, and adjusts the vehicle height by adjusting the internal pressure of the fluid chamber in stages.
