Abstract
In the rotor of the present invention, each magnet has an inward part adjoining the rotor core and an outward part positioned outward of the inward part in a radial direction of the rotor core. The outward has a facing surface which faces a stator and a pair of side surfaces which extend from two end parts of the facing surface in a circumferential direction toward the inward part. The inward part has a pair of overhanging parts which overhangs outward in the circumferential direction with respect to the pair of side surfaces of the outward part. Each locking projection of the rotor core passes between overhanging parts of two adjoining magnets and projects outward in the radial direction to engage with the overhanging parts.
