PROBLEM TO BE SOLVED: To provide a motor that is able to ensure the stability of the fixed state of a permanent magnet in a rotation body and the size accuracy of a rotor, even in a case where an anti-corrosion permanent magnet abuts on a projecting part formed on the outer periphery of the rotation body so as to project radially outward.SOLUTION: A rotor composing this motor comprises: a rotation body; and a plurality of permanent magnets 8 fixed in the outer periphery of the rotation body so as to be adjacent to one another in a circumferential direction of the rotation body. In the outer periphery of the rotation body, a plurality of projecting parts 7a, on which the fixed faces 8a of the permanent magnets 8 abut, are formed so as to project radially outward. The fixed face 8a of each of the permanent magnets 8 abuts on two projecting parts 7a. The projecting parts 7a are arranged closer to the center of the fixed faces 8a than to the circumferentially end part 8d such that the circumferential end part 8d, which is the end part of each fixed face 8a in a circumferential direction, is not in contact with the projecting parts 7a. |
