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
