摘要：
A four-wheel steering system for an automotive vehicle includes a front wheel steering mechanism operable in response to a steering effort applied thereto to steer a pair of dirigible front road wheels, a rear wheel steering mechanism including an axially displaceable operation rod operatively connected at the opposite ends thereof with a pair of dirigible rear road wheels to steer the rear road wheels, and a connecting mechanism assembled in combination with the rear wheel steering mechanism and being drivingly connected to the front wheel steering mechanism for effecting axial displacement of the operation rod in response to operation of the front wheel steering mechanism and for controlling the steering angle ratio and direction of the rear road wheels relative to the front road wheels. The rear wheel steering mechanism is in the form of a power assisted steering mechanism which includes a hydraulic power cylinder integrally provided with the operation rod, and a control valve operatively connected to the connecting mechanism and the operation rod to control fluid under pressure supplied into the power cylinder in accordance with the mode of operation of the connecting mechanism.
