Abstract
In order to position the rotor of the motor in the axial direction of the shaft, the rotor bush is placed in a prescribed position. This rotor bush comprises, all integrally machined from a planar metallic material, a shaft-contacting cylindrical wall section whose inner circumferential face constitutes a shaft press-in hole, a bearing-contacting section linked to an end of the shaft-contacting cylindrical wall section and formed in a planar shape, an outer cylindrical wall section extending from the outer circumferential side of the bearing-contacting section, and a plurality of claws formed at an end of the outer cylindrical wall section. By pressing the shaft into the shaft press-in hole of this rotor bush and bending and caulking the claws toward the surface of the shaft, the rotor bush is fixed to the shaft.
