Abstract

Air Spring and Bogie An air spring according to the present disclosure includes: an inner cylindrical member; an outer cylindrical member provided on the inner cylindrical member; a diaphragm coupled with the outer cylindrical member and the inner cylindrical 5 member; and a stopper provided rotatably with respect to a circumferential direction of the inner cylindrical member. The stopper has a raised portion raised towards the outer cylindrical member and moving on the inner cylindrical member in the circumferential direction. The outer cylindrical member has a plurality of raised portions raised toward the inner cylindrical member. The plurality of raised portions 10 of the outer cylindrical member are different in height. At least one of the outer cylindrical member's raised portion and the stopper's raised portion is restorable against circumferential deformation. [FIG. 1]
