Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the size of the driving means of a generator by reducing the cogging torque of the generator. SOLUTION: The generator comprises a neodymium magnet 18 for forming a magnetic field in an outer rotor 11, a first pole part 19 formed by arranging six poles P, each set with a magnet pole pair central angle of 32 deg., in the circumferential direction, and a second pole part 20 formed by arranging six poles P, each set with a magnet pole pair central angle of 28 deg., in the circumferential direction. Furthermore, eighteen stator teeth ST are arranged oppositely to the neodymium magnet 18 at a constant interval in the circumferential direction. Respective stator teeth ST are disposed oppositely to corresponding poles P at a different phase so that the phase of a cogging torque being generated between the stator teeth ST and the pole P is shifted.
