受装置。 A bearing casing, an oil-less metal and a ball bearing coaxially fixed at intervals in a hollow part of the bearing casing, and a rotor yoke having a main magnet are attached, and are inserted from the oil-less metal side to In a motor bearing device comprising an oil-less metal and a rotor shaft pivotally supported by the ball bearing, the rotor shaft is located near the end surface of the hollow part of the ball bearing at a position corresponding to the hollow part. An annular locking groove is formed, and a ring-shaped stopper member inserted into the outer periphery of the rotor shaft and locked in the locking groove is arranged so as to be able to abut against the inner ring of the ball bearing within the hollow portion. A motor bearing device characterized by:
