To provide an air spring capable of improving pressure resistance and horizontal allowable displacement performance.SOLUTION: A cylindrical diaphragm 5 is disposed between an upper face plate 2 and a laminated rubber 3 and a stopper 4. An upper bead portion 6 projecting to an inner face side, is disposed on an upper end portion of the diaphragm 5. The neighborhood of an end portion of an outer face of the diaphragm 5 is closely brought into contact with the upper face plate 2. The upper bead portion 6 is fitted to a connection portion 7 projected at a center of the upper face plate 2. A bead presser 8 is vertically holding the upper bead portion 6 with the upper face plate 2, is disposed. The bead presser 8 is provided with a locking projection 9 for locking the upper bead portion 6 from a radial outer side.SELECTED DRAWING: Figure 1
