Abstract
In a steering device, the rotation of the input shaft corresponding to the steering operation is transmitted to the output shaft via a rotation transmission mechanism, and is transmitted from the output shaft to the wheels of the vehicle by a steering gear so that the steering angle varies. A control device controls an electromotive actuator used to drive a constituent element of the rotation transmission mechanism in accordance with a variable quantity that expresses the traveling conditions of the vehicle, on the basis of the respective detection values of an input sensor used to detect the amount of input into the input shaft, an output sensor used to detect the amount of output of the output shaft and a traveling condition sensor used to detect the variable quantity that expresses the traveling conditions of the vehicle, so that the ratio of the transmission of rotation from the input shaft to the output shaft is altered in accordance with the variable quantity that expresses the traveling conditions.
