摘要：
A cup shaped base 12 and a cap 13 are coupled, therein coil spring 14 is accommodated to form a holder 11, and the holder is interposed between the bearing 3 of a rotor shaft 4 and a sleeve 5. Different from being directly mounted on the rotor shaft, since the base 12 is provisionally held on the rotor shaft, the operation efficiency at the time of assembling the motor is outstandingly increased.
