<p>A vehicle height adjusting device capable of kneeling without discharging air in an air spring into the atmosphere. It is possible to perform kneeling in addition to forward inclining without using supporting legs, a specific pump, and a driving device, as well as a cut-off device therefor. Furthermore, in order to do without using the aforesaid back-and-forth driving device, kneeling circuits (11a, b) to (18a, b) including air reservoir devices (11a, b) to (13a, b) are provided, and when kneeling, air inside respective air springs (13a, b) is moved to be stored in the air reservoir devices, whereby the front part or the whole of the vehicle body is caused to kneel, while when restored from the kneeling state, air stored in the air reservoir devices is returned to the respective air springs by virtue of hydraulic pressure from a hydraulic source (20) via the kneeling circuits, whereby the whole of the vehicle body is restored to its original state with a normal air suspension state that is effected by means of leveling valves (7a, b) being restored. <IMAGE></p> |
