An apparatus for positioning and cushioning the rotor shaft of a fan motor. The apparatus is mounted within a shaft tube of the motor, which also receives the rotor shaft. The apparatus generally comprises a central portion, a peripheral portion and a connecting portion. When the apparatus mounted within the shaft tube of the motor, the outer edge of the peripheral portion fits tightly against the inner wall of the shaft. The connecting portion connects the central portion to the peripheral portion, and includes a plurality of connecting pieces projecting radially outward from the central portion to the peripheral portion, thereby providing elastic effects to the apparatus for cushioning the rotor shaft, which is loaded on the central portion. In an alternate embodiment, the apparatus further comprises a plurality of hooks that are adapted to engage an annular groove on the rotor shaft, thereby locking the shaft in place within the shaft tube.
