To prevent or suppress the damage of a connector member of signal lines.SOLUTION: In an in-wheel motor drive unit (1) having a motor part (21) having a motor rotating shaft (22) which is arranged while being offset in a vehicle fore-and-aft direction from an axle (axial line O), and a casing (10) for accommodating the motor part and a deceleration part, the casing (10) has a first end face part (91) extending in a radial direction while being overlapped on a position of the motor part when viewed from the inside of a vehicle width direction, and a second end face part (92) extending in the radial direction while being positioned at the axle side rather than the first end face part. The second end face part is located outside the vehicle width direction rather than the first end face part when viewed in the radial direction, and a connector member (82) for connecting a signal line (76a) extending from a sensor (80) arranged in the casing, and a signal line (76b) extending from a vehicle body side is arranged at the second end face part.SELECTED DRAWING: Figure 3

    【課題】信号線のコネクタ部材の損傷を防止または抑制する。【解決手段】車軸(軸線O)から車両前後方向にオフセットして配置されたモータ回転軸(22)を有するモータ部(21)と、モータ部および減速部を収容するケーシング(10)とを備えたインホイールモータ駆動装置(1)において、ケーシング(10)は、車幅方向内側から見て、モータ部の位置と重なって径方向に延在する第1端面部(91)と、第1端面部よりも車軸側に位置して径方向に延在する第2端面部(92)とを有している。第2端面部は、径方向に見て第1端面部よりも車幅方向外側に位置しており、第2端面部に、ケーシング内部に配置されたセンサ(80)から延びる信号線(76a)と車体側から延びる信号線(76b)とを接続するコネクタ部材(82)が設けられている。【選択図】図3
