Provided is a vehicle power device and a generator-equipped wheel bearing device capable of separating internal spaces of the devices and preventing entry of moisture into the internal spaces, so that internal components can be kept normal. The vehicle power device includes: a wheel bearing; and an electric motor including a stator and a rotor. The vehicle power device includes a rotor casing that is a cover member covering the electric motor and a part of the wheel bearing, the part being located on an inboard side with respect to the hub flange (7), such that a separated space (Is) is defined inside the cover member. A seal member (Sc) configured to prevent entry of moisture from a press-fitting part where a hub bolt (13) is press-fitted into a bolt hole (7a) provided in the hub flange (7) is disposed near the press-fitting part. The hub flange (7) is formed with an annular groove (7b) coaxial with the hub bolt (13) in an area where a head (13a) of the hub bolt (13) comes into contact with an inboard-side surface of the hub flange, and the seal member (Sc) having a ring shape is disposed in the annular groove (7b).
