Abstract
A multi-wheel vehicle provided with at least six running wheels, that is, a pair of first running wheels serving as driving wheels, a pair of second running wheels such as castors disposed before or behind said pair of first running wheels so as to be laterally turned in the traveling direction of said vehicle, and a pair of third running wheels disposed before or behind said first running wheels. The vehicle comprises a prime mover, a speed change operation device, a steering operation device, a transmission drivingly connected with said prime mover, and a pair of running-driving axles onto which said respective first running wheels are attached. The transmission applies composite force of first equal rotational forces in the same directions and second equal rotational forces in opposite directions onto said pair of first running wheels. The speed change operation device is manipulated so as to regulate the direction and magnitude of said first rotational forces. The steering operation device is manipulated so as to regulate the direction and magnitude of said second rotational forces.
