HUB DYNAMO

To eliminate generation of noise from a laminate yoke accompanying rotation.SOLUTION: A stator body 101A is constituted by arranging a first yoke 120A on one axial side of a coil bobbin 110 and a second yoke 120B on the other side. While a first holder 160A is arranged on the other axial side of the stator body, a second holder 160B is arranged on one side, and while a tip 121a of an outer peripheral-side magnetic pole part 121 of the first yoke is arranged at a holding groove 163 of the first holder, a tip 121a of an outer peripheral-side magnetic pole part 121 of the second yoke is arranged at a holding groove 163 of the second holder. A tip of an outer peripheral-side magnetic pole is held in contact with a pair of press walls 162 on both sides of the holding groove 163.SELECTED DRAWING: Figure 9 【課題】回転に伴う積層ヨークからの異音の発生を解消する。【解決手段】コイルボビン１１０の軸方向一方側に第１ヨーク１２０Ａを配置すると共に他方側に第２ヨーク１２０Ｂを配置してステータ本体１０１Ａを構成する。ステータ本体の軸方向他方側に第１ホルダ１６０Ａを配置し、一方側に第２ホルダ１６０Ｂを配置し、第１ヨークの外周側磁極部１２１の先端１２１ａを第１ホルダの保持溝１６３に配置し、第２ヨークの外周側磁極部１２１の先端１２１ａを第２ホルダの保持溝１６３に配置する。保持溝１６３の両側の一対の押さえ壁１６２によって外周側磁極の先端を密着状態で挟持する。【選択図】図９
