ABSTRACT:
Rotaton of a steering wheel is transmitted to a steering ratio changing mechanism which displaces an output displacement member according to the steering wheel turning angle to obtain a desired steering ratio. A displacment transmission member transmits the displacement of the output displacement member to a valve member of a hydraulic switching valve and a wheel turning rod is displaced under the force of a hydraulic power cylinder in response to displacement of the valve member. The displacement transmission member is operatively connected to the output displacement member, the valve member and the wheel turning rod to be operated to displace the valve member in a predetermined direction in response to a displacement of the output displacement member and to be operated to displace the valve member in the direction opposite to the predetermined direction in response to a displacement of the wheel turning rod generated by the displacement of the valve member, so that the wheel turning rod is displaced in response to displacement of the output displacement member with the valve member being hardly displaced.
