PURPOSE:To aim at reducing noise in a vehicle air suspension unit having a variable air-volume type air spring and an auxiliary tank including a fixed volume type auxiliary air chamber, by attaching a vibration damping member or a sound absorbing member to the auxiliary air chamber. CONSTITUTION:A vibration damping member 13 is applied or coated onto the outer peripheral surface of an auxiliary tank 3 which is stacked on a main air chamber 2 such that it covers a part of a main cylinder 7 in addition to the auxiliary tank 3. With this arrangement it is possible to prevent from being generated due to the stream of air into and from the auxiliary air tank. |
