An air spring is provided, in which shifting movements of a lower bead and a lower bead receiver are markedly reduced or prevented so that the air spring can function favorably, even when large torsional stress is applied to the diaphragm of a railroad car or the like that uses bolsterless trucks. For this purpose, in the air spring that is formed to include an upper support 1, a lower support 2 arranged below the upper support 1, and a diaphragm 3 made of an elastic material and extending between the upper support 1 and the lower support 2, the lower support 2 has a lower bead receiver K that supports a lower bead 3b of the diaphragm 3, the lower bead receiver K being configured to include a bead receiver body 6 to which the lower bead 3b is fitted, and an elastic layer 9 made of an elastic material and interposed between the bead receiver body 6 and the lower support 2. |
