A air spring 10 is provided, where flex deformation of a shoulder portion in a dustcover due to the restorative force of a bellows portion during compression thereof is prevented, whereby deterioration of the life of the dustcover due to such deformation is prevented. With the air spring 10, a stopper 82 of a deformation-preventing cap 70 is arranged at the outer peripheral side of a shoulder portion 54 in a dustcover 50. At the time of compression deformation of a bellows portion 56, the stopper 82 comes into contact with the shoulder portion 54, and flex deformation of the shoulder portion 54 towards a linking tube 52 side is restricted. Due to this, the restorative force from the compression deformed bellows portion 56 via the shoulder portion 54 can be supported by the stopper 82 of the deformation-preventing cap 70. Even in a case where the rigidity of the shoulder portion 54 relative to the restorative force of the compression deformed bellows portion 56 cannot be sufficiently increased, the amount of flex deformation towards the linking tube side of the shoulder portion 54 that received the restorative force of the bellows portion 56 can be decreased.
