PROBLEM TO BE SOLVED: To enable the small turning of a car body, and to prevent the generation of a difference of the inner wheel by the handling similar to a folding type handling by simultaneously converting a front and a rear wheels in opposite directions in right and left by the same angle to each other through a transmission gear to be operated by the steering wheel operation. SOLUTION: A hydraulic pump 8 to be operated by turning a steering wheel 5 rotates a hydraulic motor 10 with the oil pressure by the motive power of an engine 9. A gear 11 is fitted to the tip of a motor shaft of the hydraulic motor 10, and the gear 11 is engaged with a gear 13 provided at a central part of a transmission driving shaft 12 so as to rotate the driving shaft 12. In a front and a rear wheels 2, 3, axles 15 are supported by steering spindles 14a, 14b for changing direction at an intermediate part thereof, and gears 17a, 17b provided in both ends of the transmission driving shaft 12 are engaged with the gears 16a, 16b fixed to the steering spindles 14a, 14b. Direction of the front and rear wheels 2, 3 can be forcibly converted in opposite directions in right and left by the same angle at the same time through the gears 16a, 16b. |
