PROBLEM TO BE SOLVED: To provide an air spring not only preventing internal interference from occurring but also enabling an increase in the durability of a diaphragm. SOLUTION: The outer tube 26 of a bush 22 is connected to the lower end face 12B of a piston 12. A chamber 14 formed to have a diameter larger than that of the piston 12 is disposed at a position just above the piston 12, and the outer tube 26 of a bush 24 is connected to the upper end face 14B of the chamber 14. The bush 22 and the bush 24 are alternately disposed in a direction orthogonal to each other so that twist in a direction different from a direction in which twist can be absorbed by the bush 22 can be absorbed. A diaphragm 16 cylindrically formed of a rubber material is disposed between the chamber 14 and the piston 12, and the diaphragm 16 is elastically deformed according to the relative displacement of the chamber 14 to the piston 12.
