PURPOSE:To improve the air sealing performance of a selector valve used in a vehicle-height adjusting apparatus, by disposing seal members around a valve element. CONSTITUTION:When an inner tube 1 is compressed, a selector valve 5 is moved upward and a lip 26 of a seal member 23 opens a port 4, so that a high pressure is introduced into an air chamber 2. Resultantly, the inner tube 1 is brought back to its original position by the high pressure, and the vehicle height is corrected. On the other hand, when the inner tube 1 is expanded, the selector valve 5 is moved downward, and a lip 24 of a seal member 21 opens a port 3, so that air in the air chamber 2 is released to the atmosphere. This causes compression of the inner tube 1, so that the vehicle height is brought back to the standard position. |
