The air spring (4) is provided with an upper surface plate (1), a lower surface plate (2), and a tubular flexible film body (3) having opposite ends respectively air-tightly connected to the surface plates (1, 2), and the air spring (4) has sealed therein a pressurized gas having a pressure higher than or equal to the atmospheric pressure. The shear spring means (6) is mounted on the lower surface plate side of the air spring (4) and is mainly subjected to shear deformation due to a vertical input.
