The steering shafts may be hollow shafts. The vehicle may further comprises a large drive gear horizontally and rotatably mounted on the body so as to be concentric with the large steering gear and connected to a drive motor, drive shafts inserted in holes of the hollow shafts so as to be rotatably supported by the hollow shafts, small drive gears meshed with the large drive gear and concentrically fixed to the drive shafts to transmit rotational force from the large drive gear to the drive shafts, and rotational force transmitting gears for transmitting the rotational force from the drive shafts to the wheels while allowing steering of the wheels.
