A front wheel is rotatably fitted to a knuckle of a suspension by means of a hub unit. While a stator bracket, which is fitted to an outer hub of the hub unit fixed to the knuckle, supports an annular stator, a rotor bracket, which is fitted to an inner hub of the hub unit to which the front wheel is fixed, supports an annular rotor, outside the stator. Rotation of the rotor is guided by a bearing of the hub unit.

In-wheel motor

A motor vehicle acquires driving power for running from a high voltage power supply. The vehicle has a collision detecting device that detects a vehicle collision, a deceleration detecting device that detects a deceleration of the motor vehicle, and a high voltage system shut-off control device that provides control such that a circuit of the high voltage power supply is broken in response to a collision detection signal from the collision detecting device. The circuit of the high voltage power supply is reconnected when the deceleration detected by the deceleration detecting device does not become equal to or greater than a predetermined value within a short period of time from the receipt of the collision detection signal. Therefore, if the vehicle has collided, the power supply is shut off immediately, and if the vehicle has not really collided, the power supply is not shut off so as to surely enable the vehicle to run.
