PROBLEM TO BE SOLVED: To improve power generation efficiency or the like by effectively guiding a magnetic flux from a magnet of a rotor to stator teeth of a stator.SOLUTION: A generator for a motorcycle comprises: a stator 33 in which a coil 37 is wound around a plurality of stator teeth 35 radially extending from the center; and a rotor 34 which is rotated around the stator 33 while installing a magnet 41 on an inner peripheral surface of a rotor yoke 40. A plurality of magnets 41 which are provided for each pair of electrodes are installed adjacently via a gap 42 in a circumferential direction of the rotor 34, and the stator teeth 35 includes tips 38 extending from a coil winding part 36 around which the coil 37 is wound to both sides in the circumferential direction. The gap 42 between the magnets 41 is set in such a manner that, when a rear end 44B of the magnet 41 in a direction of rotation is substantially matched with a centerline N of the coil winding part 36, a front end 44A in the direction of rotation of the neighboring magnet 41 including the front end 44A in the direction of rotation opposing the rear end 44B in the direction of rotation is prevented from being overlapped with the tips 38 of the stator teeth 35. |
