Abstract

Air Spring and Bogie An air spring includes: an outer cylindrical member; an inner cylindrical member combined with the outer cylindrical member; a diaphragm which couples the 5 outer cylindrical member and the inner cylindrical member and forms an internal space between the outer cylindrical member and the inner cylindrical member; a stopper assembly which is disposed in the internal space to be pivotable on the inner cylindrical member and can prevent the outer cylindrical member from moving toward the inner cylindrical member more than necessary; and a pivoting mechanism which causes this 10 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 15 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.
