<p>A four-wheel steering system in a wheeled vehicle the front wheel steering mechanism (10) of which is drivingly interconnected to a rear wheel steering mechanism to steer the rear road wheels (WR) in either the same or the opposite direction as the front road wheels (WF) in dependence upon the turn-angle of the steering wheel (WS) of the vehicle. In the steering system, the rear wheel steering mechanism includes an operation rod (30) operatively connected at the opposite ends thereof to the rear road wheels (WR), and a connecting mechanism (A) is assembled in combination with the rear wheel steering mechanism for effecting axial displacement of the operation rod (30) in response to operation of the front wheel steering mechanism (10) and for controlling the displacement direction of the operation rod (30) in dependence upon the turn-angle of the steering wheel.</p> |
