PROBLEM TO BE SOLVED: To provide a bicycle generator capable of efficiently generating electric power.SOLUTION: A bicycle generator 10 includes a first member 1, a second member 2, a third member 3, and a coil member 4. The first member 1 and the third member 3 are rotatable around a central axis. The first magnetic pole group of the first member 1 includes a plurality of magnetic poles arranged so as to alternately have different polarities in the circumferential direction. The second magnetic pole group of the second member 2 includes a plurality of magnetic poles arranged so as to alternately have different polarities in the circumferential direction. Magnetic members 31 of the third member 3 are arranged with a space in the circumferential direction. The third member 3 is disposed between the first member 1 and the second member 2 in the radial direction. Each magnetic member 31 has a plurality of magnetic material pieces laminated in the circumferential direction.SELECTED DRAWING: Figure 8 【課題】効率的に電力を生成することができる自転車用発電機を提供する。【解決手段】自転車用発電機１０は、第１部材１と、第２部材２と、第３部材３と、コイル部材４とを備える。第１部材１及び第３部材３は、中心軸線周りに回転可能である。第１部材１の第１磁極群は、周方向において交互に異極性となるように配置された複数の磁極を含む。第２部材２の第２磁極群は、周方向において交互に異極性となるように配置された複数の磁極を含む。第３部材３の各磁性体３１は、周方向に互いに間隔をあけて配置される。第３部材３は、径方向において第１部材１と第２部材２との間に配置される。各磁性体３１は、周方向に積層される複数の磁性体片を有する。【選択図】図８
