PROBLEM TO BE SOLVED: To provide an air spring improving the durability of a diaphragm by avoiding the collision of a stopper against a diaphragm part on the inside in the width direction of a vehicle body when a vehicle body rolls. SOLUTION: The air spring comprises the diaphragm 1, an upper plate 2, and a piston 3 whose upper end 6 is mounted to the lower end 1B of the diaphragm 1 while a mounting part 7 on the lower end 3B side is mounted to an axle S. The stopper 8 limiting the relative displacement of the piston 3 and upper plate 2 is provided in a state of projecting into a gas chamber H in the diaphragm 1 from the upper end 9 of the piston 3, and the mounting part 6 is located deviating to the width direction inner side D1 of the vehicle body F with respect to an axis O2 of the piston 3 so that the axis O2 of the piston 3 is located deviating to the width direction outer side D2 of the vehicle body F with respect to the axis O1 of the upper plate 2 in the assembled state of mounting the upper plate 2 to the vehicle body F and mounting the mounting part 6 of the piston 3 to the axis S.
