Patent abstract
In a motor, an upper surface of a flange portion of a shaft is arranged axially below a bottom end surface of a rotor core. A spacer having an axial thickness slightly greater than that of the flange portion is arranged on a radially outer side of the flange portion. A bottom surface of the spacer makes contact with an end plate whose inner circumferential surface has a radius, centered about a central axis, smaller than a radius of the flange portion. The end plate is secured to the rotor core via a fixing member.
