PURPOSE:To all directionally perform running of a vehicle, by independently connecting each driven wheel to a reversibly rotatable driving source. CONSTITUTION:When a driving truck 7 and driven truck 4 are locked in the same direction by a stopper, if driving wheels 6a, 6b are rotated in the same direction at an equal speed, a vehicle is forward and reversely moved as shown by arrow heads A, B. If the driving wheels 6a, 6b are reversely rotated at an equal speed, the driven truck 4 is only rotated in that place as shown by an arrow head C and not shifted. Where the vehicle is rotated at a desired angle, if direction of rotation of the driving wheels 6a, 6b is equalized, the truck 4 can be moved longitudinally in the direction of said desired angle. Further if only one wheel is driven or the both wheels are rotated in the same direction but changed with their rotary speed, the truck 4 can be changed with the direction while being forward or reversely moved. |
