Abstract

PURPOSE:To make air-tight while to facilitate the assembling and the disjointing work, by making the diameter at the joint between a tubular rubber film and the upper face board or the outer tube of an air spring shorter than the effective diameter of the air spring at the standard height thereby assuring the effective air damping. CONSTITUTION:An air spring 10 has the upper end of a tubular rubber film 15 coupled to an upper face board 14 applied with a protective rubber 13 and the lower end coupled to an inner tube 16, where the diameter Do at the joint of the rubber film 15 to the upper face board 14 is made shorter than the effective diameter De of the air spring at the standard height. The rubber resilient members 11a-11e at each step coupled below the air spring 10 has a hole conducting to an auxiliary air chamber 12 at the central portion. The air in said chamber 12 conducting to the air spring 10 below the fifth step rubber resilient member 11 will flow into and out of the air spring 10 through a diaphragm 18 provided at the central portion of a tube 16.
