く設定したことを特徴とする車高調整装置。 a fluid spring chamber for vehicle height adjustment interposed between the vehicle body and the axle; and a fluid spring chamber interposed between the vehicle body and the axle;
Mechanically linked to changes in vehicle height, fluid is discharged from the fluid spring chamber when the vehicle height is higher than the set neutral range, and fluid is discharged from the fluid supply source when the vehicle height is lower than the set neutral range. In a vehicle height adjustment device comprising a leveling valve that supplies fluid to a spring chamber and stops supplying and discharging fluid from the fluid spring chamber when the vehicle height is within the same set neutral range, the fluid spring chamber and the fluid supply a fluid supply device comprising: a bypass passage connected to a source with the leveling valve bypassed; and a supply control valve that supplies fluid from the fluid supply source to the fluid spring chamber via the bypass passage; When the vehicle height sensor detects the displacement between the vehicle body and the axle, and the vehicle height detected by the vehicle height sensor is lower than the set vehicle height, which is set closer to the lower vehicle height than the neutral range set by the leveling valve. A vehicle height adjustment device comprising: a controller for opening the supply control valve; and a vehicle height adjustment device, wherein the fluid supply amount per unit time of the fluid supply device is set to be larger than the fluid supply amount per unit time of the leveling valve.
