摘要： An air spring includes: an outer cylindrical member; an inner cylindrical member; a diaphragm which couples the outer and inner cylindrical members and forms an internal space; a stopper assembly disposed in the internal space; and a pivoting mechanism which causes this stopper assembly to pivot on the inner cylindrical member. The stopper assembly has a stopper portion protruding towards the outer cylindrical member, and the outer cylindrical member has as a set four or more protrusion portions provided at a position to face the stopper portion and protruding toward the inner cylindrical member. Each of the protrusion portions belonging to the set is disposed successively and also different in height. Each of the protrusion portions belonging to the set is arranged without having a protrusion portion belonging to the set smallest in height adjacent to a protrusion portion belonging to the set largest in height.
