The first magnet group includes a plurality of first magnets arrayed in a circumferential direction of the rotor. The second magnet group includes a plurality of second magnets arrayed in the circumferential direction. The first magnet and the second magnet, which are adjacent to each other and have the same polarity, are shifted from each other by a certain angle in the circumferential direction. One of the first core member and the second core member has a first recessed portion, and another of the first core member and the second core member has a first protruding portion to be engaged with the first recessed portion in the circumferential direction.
