PROBLEM TO BE SOLVED: To reduce inertia weight around a virtual kingpin shaft, and prevent an increase in steering force without deteriorating fuel consumption. SOLUTION: A wheel-in motor 5 is installed on an axle 3 for rotatably supporting a wheel 1 via speed reducer 7. A shock absorber 11 is arranged between the wheel-in motor 5 and a car body 9. The center of gravity G of a rotary part (such as the wheel 1, the axle 3 and the motor 5) for rotating at steering time is set on the virtual kingpin shaft 17 for connecting an upper mount 13 being a car body side installing part of the shock absorber 11 and a lower ball joint 15 being an axle side installing part of a suspension link for connecting the axle 3 and the car body under the wheel-in motor 5.
