Comprising a motor, a speed reduction device, a differential device and a cylindrical shell. The motor has a rotor and a stator. The rotor rotates about a motor axis. The stator and the rotor face each other in the radial direction with a gap therebetween. The reduction gear has a planetary gear mechanism and can increase the rotational power output from the motor in accordance with a reduction ratio. The differential device distributes and outputs the rotational power from the reduction gear. The housing accommodates the motor, the speed reduction device, and the differential device so that the motor, the speed reduction device, and the differential device are arranged in the axial direction with the motor axis as a common rotation axis. The housing includes a first mounting portion and a second mounting portion disposed on an outer peripheral surface. The first mounting portion and the second mounting portion are disposed on opposite sides in a direction perpendicular to the axial direction with respect to the motor axis.
包括马达、减速装置、差动装置及筒状的外壳。马达具有转子及定子。转子以马达轴线为中心旋转。定子与转子在径向上隔着间隙相对。减速装置具有行星齿轮机构,能根据减速比使从马达输出的旋转动力增大。差动装置对来自减速装置的旋转动力进行分配并输出。外壳将马达、减速装置及差动装置收纳为以所述马达轴线为共用的旋转轴线在轴向上排列。外壳具有配置于外周面上的第一安装部及第二安装部。第一安装部和第二安装部相对于马达轴线配置在与轴向垂直的方向上的相反侧。
