To provide a vehicular in-wheel motor drive unit which is suppressed in the generation of vehicle body vibration resulting from the eccentricity of a center of gravity of an electric motor, and suppressed in the lowering of a riding comfort of the vehicle.SOLUTION: A reduction gear side end part 16a of a motor rotating shaft 16 is supported by a reduction gear part 30 so as to be rotatable and cantilevered, and a connecting device 42 for connecting a motor part 18 to the reduction gear part 30 via an elastic member 44c is arranged between the motor part 18 and the reduction gear part 30. Therefore, even if a drive force of the electric motor 14 is changed or a vehicular in-wheel motor drive unit 10 vertically vibrates, since the motor part 18 is connected to the reduction gear part 30 by the connecting device 42 via the elastic member 44c and a change of the drive force of the electric motor 14 and vibration accompanied by the vertical movement of the vehicular in-wheel motor drive unit 10 are absorbed, the generation of vehicle body vibration resulting from the eccentricity of a center of gravity of the electric motor 14 and the lowering of a riding comfort of a vehicle are suppressed.SELECTED DRAWING: Figure 1

    【課題】電動モータの重心の偏心に起因する車体振動の発生が抑制され、車両の乗り心地の低下が抑制される車両用インホイールモータ駆動装置を提供する。【解決手段】モータ回転軸16の減速機側端部16aが減速機部30によって回転可能に且つ片持ち状に支持され、モータ部18と減速機部30との間には、モータ部18を弾性部材44cを介して減速機部30に連結する連結装置42が設けられている。このため、電動モータ14の駆動力変化や車両用インホイールモータ駆動装置10の上下振動があっても、モータ部18は弾性部材44cを介して連結装置42によって減速機部30に連結されていて、それら電動モータ14の駆動力変化や車両用インホイールモータ駆動装置10の上下動に伴う振動が吸収されるため、電動モータ14の重心の偏心に起因する車体振動の発生や、車両の乗り心地の低下が抑制される。【選択図】図1
