<p>PURPOSE:To arrange a rear wheel steering mechanism and a rear wheel operating device at the optimum positions without being restricted by a fuel tank having a large capacity by installing the rear wheel steering mechanism onto a car body and supporting the rear wheel operating device by the rear wheel steering mechanism. CONSTITUTION:A four-wheel driving device transmits the revolution of a propeller shaft 7 onto which the power of an engine 1 is transmitted, into the right/left rear wheel driving shaft 5 through a rear wheel operating device 4, and revolves the right and left rear wheels 6. Further, the four-wheel steering device steers the right and left front wheels 3 by a front wheel steering mechanism 9 according to the operation of a steering wheel 8, and the right and left rear wheels 6 are steered by a rear wheel steering mechanism 10 according to steering, and the front and rear wheel steering mechanisms 9 and 10 are connected by a connecting shaft 11. In this case, the rear wheel steering mechanism 10 is mounted by a bolt 6 onto the upper surface part at a car body center line position by the cross member 13 of a car body frame, and the rear wheel operating device 4 is arranged at the immediately front position of the rear wheel steering mechanism 10 and the cross member 13.</p> |
