Summary:PROBLEM TO BE SOLVED: To provide an electric motor capable of being fixed to a yoke with an energization member having a sufficiently large elastic force even for a magnet in which a gentle corner part is formed on an inner circumferential surface side of a terminal part.SOLUTION: An electric motor 10 includes: a yoke 12 of a bottomed cylindrical shape; a plurality of magnets 14a, 14b, 14c disposed along an inner wall of the yoke 12; and a tabular energization member 44 disposed between facing terminal parts of neighboring magnets. The energization member 44 includes: a pair of pressing parts 50 being in contact with the magnets 14a, 14b, 14c to energize; and a coupling part 48 for coupling the pair of pressing parts 50. The coupling part 48 is formed with a width wider than a width of the pressing part 50.SELECTED DRAWING: Figure 3 【課題】端部の内周面側に緩やかな角部が形成されるマグネットであっても、これを十分大きな弾性力を有する付勢部材によってヨークに固定できる電動モータを提供する。【解決手段】電動モータ１０は、有底円筒状のヨーク１２と、ヨーク１２の内壁に沿って配設される複数のマグネット１４ａ、１４ｂ、１４ｃと、隣接するマグネットの対向する端部間に配設される板状の付勢部材４４とを備え、付勢部材４４は、マグネット１４ａ、１４ｂ、１４ｃに当接して付勢する一対の押圧部５０と、一対の押圧部５０を連結する連結部４８とを備え、連結部４８は押圧部５０よりも幅広に形成されている。【選択図】図３
