VEHICLE DRIVING APPARATUS

摘要

A vehicle driving apparatus in which a rotor of a rotating electrical machine can be supported to be capable of rotating appropriately and a rotation sensor can be disposed compactly is realized. The vehicle driving apparatus includes a rotating electrical machine MG serving as a drive power source of the vehicle and a rotation sensor 13 that detects a rotation position of a rotor Ro of the rotating electrical machine MG. The rotating electrical machine MG includes a rotor supporting member 22 that supports the rotor Ro from a radial direction inner side, and the rotor supporting member 22 includes a cylindrical supporting cylindrical portion 25 that extends in an axial direction. The supporting cylindrical portion 25 includes a first tubular portion 26 and a second tubular portion 27, an inner peripheral surface and an outer peripheral surface of the second tubular portion both having a smaller diameter than an inner peripheral surface and an outer peripheral surface of the first tubular portion. A support bearing 61 that supports the rotor supporting member 22 rotatably is disposed to contact the inner peripheral surface of the first tubular portion 26, and a sensor rotor 14 of the rotation sensor 13 is disposed to contact the outer peripheral surface of the second tubular portion 27.
