  "textContent": "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, such that a separated space is defined inside the cover member. A seal member configured to prevent entry of moisture from a press-fitting part where a hub bolt is press-fitted into a bolt hole provided in the hub flange is disposed near the press-fitting part. The hub flange is formed with an annular groove coaxial with the hub bolt in an area where a head of the hub bolt comes into contact with an inboard-side surface of the hub flange, and the seal member having a ring shape is disposed in the annular groove.",
