Abstract
To provide an outer rotor type motor capable of suppressing the runout of a top surface by improving the strength in a fitted part between a rotor yoke and a rotor shaft and suppressing resonance between vibration generated by rotation of a rotated body to be a load and motor vibration to thereby realize noise reduction. A rotor yoke is configured so that a rotor hub is fitted to a top surface portion formed in a cup shape integrally with a rotor shaft, and a reinforcing hub concentrically fixed to the rotor shaft with the rotor yoke is arranged so as to overlap the rotor hub.
