PROBLEM TO BE SOLVED: To provide a power generator for bicycle capable of efficiently generating power.SOLUTION: A power generator for bicycle 10 comprises a first member 1, a second member 2, a third member 3, and a coil member 4. The first member 1 and third member 3 are rotatable around the center axis line. The first member 1 includes a first magnetic pole group including a plurality of magnetic poles arranged so as to alternately have opposite polarity in the circumferential direction. The second member 2 includes a second magnetic pole group including a plurality of magnetic poles arranged so as to alternately have opposite polarity in the circumferential direction. The number of the magnetic poles of the second magnetic pole group is larger than the number of the magnetic poles of the first magnetic pole group. The third member 3 includes magnetic materials 31 arranged so as to be spaced from each other in the circumferential direction. The third member 3 is disposed between the first member 1 and second member 2 in the radial direction.

    【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2磁極群の磁極数は、第1磁極群の磁極数よりも多い。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。【選択図】図3
