Abstract
Front wheels ( ) are attached to transmission devices ( ) which are mounted to the vehicle body ( ) to be rotatable around vertical axes ( ), and rotating means ( ) are provided between the side of the vehicle body ( ) and the transmission devices ( ), whereby the front wheels are steered to turn laterally at substantially right angles. An electric motor ( ) is attached to the transmission device ( ) to be located under the vertical axis ( ). A case body ( ) of the electric motor ( ) is constructed by an outer case part ( A) and a non-loaded side bracket ( B), and a loaded side end portion of the outer case-part ( A) is connected to the transmission device case body ( ). The drive shaft ( ) is rotatably supported by the non-loaded side bracket ( B) at one end and by the transmission device case body ( ) at the other end. A driving portion ( ) provided at the other end side of the drive shaft ( ) is operatively connected to an axle ( ). As a result, a traveling drive device section can be constructed to be compact with assembling easiness.
