Provided is a vehicle power device and a generator-equipped wheel bearing device capable of separating an interior of the device to protect internal components from water which could potentially penetrate to the interior through press-fitting areas of bolts or the like. The vehicle power device (1) includes a wheel bearing (2) and an electric motor (3) including a stator (18) and a rotor (19). The wheel bearing (2) includes an outer ring (4) and an inner ring (5) rotatably supported by the outer ring (4) through rolling elements (6), the inner ring (5) including a hub flange (7) configured to be attached with a wheel of a vehicle. The vehicle power device includes: a rotor case (15) that covers the electric motor (3) and an inboard-side part of the wheel bearing located on an inboard side with respect to the hub flange (7) to define a separated space therein; and an annular seal component (Sc) that covers, from the inboard side of the hub flange (7), head parts (13a) of a plurality of hub bolts (13) press-fitted into the hub flange (7) and a surrounding area thereof.
