PROBLEM TO BE SOLVED: To provide an improved air spring capable of preventing generation of foreign sound and noise caused by that an elastic body is kept into contact with a large-diameter plate-shaped member and compressed while rubbing the same, in an air spring provided with the elastic body exerting damping action by contact in excessive cushioning.SOLUTION: In an air spring having a cylindrical rubber film 1, a large-diameter plate-shaped member 2, and a piston 3, and having a peripheral face 3c capable of rolling and guiding a reversed cylindrical portion 1C folded at the other end portion side, on the piston 3, an elastic body 14 is disposed on the piston 3, a slip sheet 20 is disposed on the large-diameter plate-shaped member 2, and the elastic body 14 and the slip sheet 20 are brought into contact with each other in accordance with reduction of an interval in an axial center P direction of the piston 3 and the large-diameter plate-shaped member 2 by a prescribed amount. The slip sheet 20 is composed of a material having frictional force to the elastic body 14, smaller than frictional force of the large-diameter plate-shaped member 2 and the elastic body 14.SELECTED DRAWING: Figure 1 |
