A vehicle height adjusting device includes an air compressor, an air tank storing pressurized air produced in the air compressor, a dehumidifying device provided between the air compressor and the air tank, and an elevating device for elevating or descending the height of a vehicle and receiving pressurized air from the air tank or from the air compressor in elevating the height of the vehicle and exhausting pressurized air therefrom through the dehumidifying device to atmosphere in descending the height of the vehicle. There are provided a pressure detector detecting the pressure in the air tank, a height detector detecting the height of the vehicle, and a controlling circuit connected to the pressure detector and the height detector for controlling the operation of the elevating device in accordance with the output signal of the height detector and that of the air compressor in accordance with the output signals of the pressure detector and the height detector.
