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 coupling the outer cylindrical member and the inner cylindrical member to each other, the diaphragm 5 providing an internal space between the outer cylindrical member and the inner cylindrical member, a stopper assembly arranged in the internal space as being pivotable over the inner cylindrical member, the stopper assembly allowing suppression of movement of the outer cylindrical member toward the inner cylindrical member more than necessary, a pivoting mechanism pivoting the stopper assembly over the 10 inner cylindrical member, and a space portion provided between the stopper assembly and the inner cylindrical member, the space portion allowing lowering in resistance in pivot of the stopper assembly.
