To provide a motor unit and an electrically-driven power steering device capable of reducing weight and improving compatibility with electromagnetic environment.SOLUTION: An electric motor 2 includes a cylindrical motor case 21, a gearbox 23 which is a conductor arranged at one end of the motor case 21, and a motor terminal 25. A control device 3 includes a control device case 31 supported to the electric motor 2 and a connector 35 having three connection terminals 355 to which the motor terminal 25 is connected. The gearbox 23 includes a cover portion 4 that covers a part of the connector 35. The cover portion 4 overlaps with the whole connectors 35 when viewed from an axial direction (Z direction) of the electric motor 2, overlaps with at least the part of the connector 35 when viewed from a direction (Y direction) orthogonal to both an arrangement direction (X direction) and the axial direction (Z direction) in which the three connection terminals 355 are arranged, and does not overlap with the connector 35 when viewed from the arrangement direction (X direction).SELECTED DRAWING: Figure 4
【課題】軽量化でき且つ電磁環境適合性を向上できるモータユニット及び電動パワーステアリング装置を提供すること。【解決手段】電動モータ2は、筒状のモータケース21、モータケース21の一端に配置される導体であるギヤボックス23、及びモータ端子25を備える。制御装置3は、電動モータ2に支持される制御装置ケース31、及びモータ端子25が接続される3つの接続端子355を有するコネクタ35を備える。ギヤボックス23は、コネクタ35の一部を覆うカバー部4を備える。カバー部4は、電動モータ2の軸方向(Z方向)から見た場合にコネクタ35の全部と重なり、3つの接続端子355が並ぶ配列方向(X方向)及び軸方向(Z方向)の両方に対して直交する方向(Y方向)から見た場合にコネクタ35の少なくとも一部と重なり、配列方向(X方向)から見た場合にコネクタ35と重ならない。【選択図】図4
