Abstract
A bearing device for use with of a motor, includes a worm-like thread, which is threaded to a rotor shaft, and which engages a worm wheel. The rotor shaft is supported by a pair of radial bearings. When the rotor shaft is not caused to bend, a third radial bearing is spaced away from the outer peripheral surface of the rotor shaft. When the rotor shaft is caused to bend under the counter force generated by the worm wheel, the rotor shaft is supported by the third radial bearing along the bend direction.
