Abstract
Front wheels and rear wheels are mounted to a vehicle body to be steerable by 90 degrees. Right and left front wheels are connected to the turning members which are capable of rotating around vertical axes in relation to the vehicle body though individual electric drive motors. Each electric motor has an external casing integrally formed with each turning member, and allows a drive shaft and a rotor to be accommodated and rotatable therein. Each drive shaft is connected to the front wheel, and an apparatus for rotating the turning member is provided. This allows the driving front wheels to be steered straight sideways and the electric motor to be readily assembled and arranged compact.
