ABSTRACT:
In the motor, the compound bearing assembly is assembled from stepped-diameter shaft 1, sleeve-like outer race ring 5, first balls 4, second balls 8a, and inner race ring 7 a, and has a base-end portion of large-diameter portion la of the stepped-diameter shaft 1 fixedly mounted on a base member 10 of the motor at right angles to permit the stepped-diameter shaft 1 to extend upward. After that, the compound bearing assembly is fixedly mounted in a central hub portion 12 of a rotor 11 of the motor in an insertion manner to complete the motor provided with the compound bearing assembly. Consequently, it is easy for the motor manufacturer to assemble his product or motor with the compound bearing assembly at high accuracy. (See FIG. 1)
