PROBLEM TO BE SOLVED: To provide an air spring to obtain a moving vehicle which realizes a comfortable ride even when passing through a curve. SOLUTION: An air spring for a moving body which is provided with an outer cylinder, a lower surface plate, a diaphragm, and a rubber stopper provided between the lower surface plate and a holding plate, is equipped with a displacement restriction mechanism for the rubber stopper which consists of a first stop member provided on one of the holding plate and lower surface plate and second stop members provided on the other. Stop wall surfaces are shaped so that distances between the first stopper and the second stoppers is decreased as the amount of displacement along the arc is increased in a relative positional relationship between the first stop member and the second stop members when the first or second stop member is displaced to form an arc with a truck axle of a truck in the moving body as the center.
