Provided is a vehicle power device and a wheel bearing device equipped with a generator that are able to maintain the internal components in a normal state by isolating the inside of the devices and preventing water from entering inside the devices. This vehicle power device is provided with a wheel bearing, and an electric motor having a stator and a rotor. A rotor case is provided, which is a covering means for covering the electric motor and for covering a portion on the inboard side relative to a hub flange (7) of the wheel bearing so as to cause the inside to be an isolated space (Is). Further, a seal material (Sc) for preventing water from entering into a bolt hole (7a) provided to the hub flange (7) from a press-fit portion where a hub bolt (13) is press-fitted, is provided around the press-fit portion. In a portion that is in the inboard side surface of the hub flange (7) and that comes into contact with a head (13a) of the hub bolt (13), an annular groove (7b) is formed coaxially with the hub bolt (13). The seal material (Sc) having a ring shape is provided to the annular groove (7b).
提供一种车辆用动力装置和带有发电机的车轮用轴承装置,其能够通过隔离装置内部并防止水分进入装置的内部,确保内部部件的正常状态。设置作为覆盖机构的转子壳体,该覆盖机构覆盖车轮用轴承的轮毂法兰(7)的内侧的部分和电动机,以内部为隔离空间。另外,密封件(Sc)设置在上述压配合部位的周边,该密封件(Sc)防止水分从压配合在开设于轮毂法兰(7)中的螺栓孔(7a)的压配合部位而浸入的情况。在轮毂法兰(7)的内侧面中的轮毂螺栓(13)的头部(13a)所接触的部分,形成与轮毂螺栓(13)相同轴心的环状槽(7b),在该环状槽(7b)中设置环形状的密封件(Sc)。
