ABSTRACT:
A vehicle height adjusting apparatus includes air spring portion, an air supply source, a switching valve causing a total air volume of the air spring portion to be constituted by only a main air chamber and by a sum of the main air chamber and a sub air chamber, an auxiliary valve, operating state determining portion for determining an operating state of the vehicle, and controlling portion for controlling the adjusting valve, the switching valve and the auxiliary valve. The controlling portion controls the adjusting valve and the switching valve to shift to closed positions so as to close the first and second passages, respectively, and controls the auxiliary valve to shift to an open position so as to open the third passage and to discharge air in the sub air chamber by a predetermined amount through the air supply source and then controlling the auxiliary valve to shift to a closed position so as to close the third passage in a case that the operating state determining means determines that the vehicle is in one of the transition state and the stopped state.
