To provide a motor unit having a resolver that has an increased accuracy in detecting a rotation angle.SOLUTION: A motor unit 1 has a motor 20, and a resolver 10 that detects the rotation angle of a rotation shaft 23 of the motor 20. The resolver 10 comprises a resolver rotor 11, a retainer 40 fixed to the rotation shaft 23, and connection members 51 connecting the resolver rotor 11 and the retainer 40 to each other. The resolver rotor 11 has an insertion hole 111 allowing insertion of the rotation shaft 23 with an interval between the rotation shaft 23 and the insertion hole. The retainer 40 includes a press-fit hole 41 to which the rotation shaft 23 is press-fit and fixed.SELECTED DRAWING: Figure 2 【課題】回転角度の検出精度を高めたレゾルバを有するモータユニットを提供する。【解決手段】モータ２０と、モータ２０の回転軸２３の回転角度を検出するレゾルバ１０と、を有するモータユニット１であって、レゾルバ１０は、レゾルバロータ１１と、回転軸２３に固定されるリテーナ４０と、レゾルバロータ１１とリテーナ４０とを連結する連結部材５１と、を備え、レゾルバロータ１１は、回転軸２３との間に間隔を有した状態で当該回転軸２３を挿通させる挿通孔１１１を備え、リテーナ４０は、回転軸２３が圧入固定される圧入孔４１を備える。【選択図】図２
