PROBLEM TO BE SOLVED: To provide an air spring that clearly suppresses or prevents lag motion between a lower bead part and a lower bead receiving part so as to achieve a satisfactory function even when a strong torsion stress is exerted on a diaphragm of a rolling stock using a bolster-less bogie, or the like.SOLUTION: An air spring includes: an upper support part 1; a lower support part 2 disposed below the upper support part 1; and a diaphragm 3 made of an elastic material disposed so as to extend over the upper support part 1 and the lower support part 2. A lower bead receiving part K that supports a lower bead part 3b of the diaphragm 3 in the lower support part 2 includes: a bead receiving body 6 that permits fitting of the lower bead part 3b; and an elastic layer 9 made of an elastic material interposed between the bead receiving body 6 and the lower support part 2. |
