Abstract: An air spring structure, for preventing the shaking of a suspended rotator by absorbing/preventing the vibrations of the rotator in a commercial or household machine, comprises a body made of soft rubber materials, the body being provided with an inner cylindrical and outer cylindrical portion and an upper and lower supporting portions to thereby form an annular air chamber therein, a longitudinal through hole being defined by an inner cylindrical portion at the center. The hardness of the soft rubber materials forming the body are below 30 to 40 Shore (A). The thicknesses of the inner cylindrical portion and the outer cylindrical portion are thinner than those of the upper and lower supporting portions, and the ratio of horizontal stiffness (kh) to vertical stiffness (kv) is between 0.7 to 1.
