A rotating electrical machine includes a cylindrical rotor and a cylindrical stator. The rotor includes a magnet portion. The stator includes a multiple-phase stator winding. The rotor and the stator are arranged in a state in which the magnet portion and the stator winding oppose each other inward and outward in a radial direction. A differential apparatus includes a differential case, side gears, and a pinion gear. The differential case rotates with a rotation of a rotor. The side gears are housed in the differential case and respectively connected to the pair of axles. The pinion gear is housed in the differential case and mutually meshes with the side gears. The differential apparatus is concentrically arranged with the rotor in a hollow portion provided on an inner side in a radial direction of a magnetic circuit portion configured by the rotor and the stator in the rotating electrical machine.
