Air spring and bogie

An air spring comprising:

• 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 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 handle for pivoting the stopper assembly over the inner cylindrical member;
• a guide member attached to the handle as rising from the handle;
• a positioning member attached by insertion in a guide hole in the guide member for positioning of the handle;
• a positioning hole provided in the inner cylindrical member which can receive the positioning member;
• and
• a holding mechanism for holding the positioning member in the inner cylindrical member with the positioning member being inserted in the positioning hole,
• a position of the stopper assembly with respect to the inner cylindrical member being determined by inserting the positioning member in the positioning hole.
