To dispense with a shaft stopper due to conventional rigid body con tact by increasing a spring constant itself of the lateral direction of a laminated rubber more than that of the longitudinal direction and thereby mitigate impact in rolling, in an air spring constituted of the laminated rubber and a rubber diaphragm connected to the upper end of the laminated rubber.

In an air spring provided with laminated rubber 20 made by alternately laminating a plurality of sheets of rubber plates 22 and hard plates 23 and a rubber diaphragm 7 connected to the upper end of this laminated rubber 20, linear projecting streaks 23b and recessed grooves in which the rubber plates 22 and the hard plates 23 are engaged with each other are provided and these projecting streaks 23b and recessed grooves are provided each other in parallel in a plurality of sheets of rubber plates 22 and hard plates 23.
