In a case where the electric vehicle has four wheels including left and right front wheels and left and right rear wheels, an in-wheel motor driving device is incorporated only in the left and right front wheels, only in the left and right rear wheels, or in all of the wheels. An independent-steering apparatus serves for all of the wheels. A kingpin axis in each of the wheels makes an intersection with a road surface on a circle inboard of a vehicle chassis.
