Power device for vehicles

A power device for a vehicle comprising:

• a wheel bearing including a stationary ring and a rotary ring having a hub flange, the rotary ring being rotatably supported by the stationary ring via rolling elements, the hub flange being configured to be attached with a wheel of the vehicle and a brake rotor;
• and
• a generator including a stator attached to the stationary ring of the wheel bearing and a rotor attached to the rotary ring of the wheel bearing,
• wherein the rotor includes a soft magnetic material part, magnets, and a resin material part that is integrally molded with the soft magnetic material part and the magnets, and
• the brake rotor is attached to the hub flange through the resin material part, and the brake rotor includes a plate-like part and an outer peripheral part extending from the plate-like part toward an outer peripheral side of an outer ring;
• the resin material part of the rotor forms a case of the generator;
• a bottom part of the resin material part is overlapped with the plate-like part of the brake rotor;
• and
• the plate-like part of the brake rotor is attached to the hub flange through the bottom part of the resin material part.
