Summary:To provide a motor having a structure which enables a bus bar unit to be positioned relative to a bearing holder with high accuracy.SOLUTION: A motor 10 includes: a rotor 30 having a shaft 31; a stator 40; a bearing 82 rotatably supporting the shaft 31; a bearing holder 50 which holds the bearing 82; and a bus bar unit 60 which is located above the bearing holder 50 and supplies driving current to the stator 40. The bus bar unit 60 has: a bus bar 90; and a bus bar holder 61 which holds the bus bar 90. The bus bar holder 61 has: a holder body part 63a; and a fitting protruding part protruding downward from the holder body part 63a. An upper surface of the bearing holder 50 has a fitting hole part. A lower end part of the fitting protruding part is located at the radial inner side of the fitting hole part.SELECTED DRAWING: Figure 1 【課題】バスバーユニットをベアリングホルダに対して精度よく位置決めできる構造を有するモータの提供。【解決手段】モータ１０は、シャフト３１を有するロータ３０と、ステータ４０と、シャフト３１を回転可能に支持するベアリング８２と、ベアリング８２を保持するベアリングホルダ５０と、ベアリングホルダ５０の上側に位置しステータ４０に駆動電流を供給するバスバーユニット６０と、を備える。バスバーユニット６０は、バスバー９０と、バスバー９０を保持するバスバーホルダ６１と、を有し、バスバーホルダ６１は、ホルダ本体部６３ａと、ホルダ本体部６３ａから下側に突出する嵌合突出部と、を有し、前記ベアリングホルダ５０の上面は、嵌合穴部を有し、嵌合突出部の下側の端部は、嵌合穴部の径方向内側に位置する。【選択図】図１
