To provide a vehicle power device and a generator-equipped wheel bearing device which can prevent electrolytic corrosion of wheel bearings and can be maintenance-free with respect to a function of insulation.SOLUTION: The vehicle power unit includes: a wheel bearing 2 having an outer wheel 4, double-row rolling body 6, and an inner wheel 5; and a motor generator 3 including a stator 18 and a rotor 19. The stator 18 and the rotor 19 of the motor generator 3 are smaller in diameter than an outer peripheral portion 12b of a brake rotor 12. The whole except an attachment to a hub flange 7 in the motor generator 3 is located in an axial range L1 between the hub flange 7 and an outboard side surface of a knuckle 8. An insulating layer 9 is interposed between a stator holding member 24 which is an intermediate member and the outer wheel 4.SELECTED DRAWING: Figure 1
