Abstract
In a vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and tires to change the transmission ratio, and an ECU for variably controlling the variable gear ratio unit in accordance with the state of a vehicle, the variable gear ratio unit includes a motor controlled by the ECU, and a reducing mechanism which has a transmission ratio for allowing to maintain the steering angle of the steering wheel with respect to an RF reverse input and transmits the rotation of the motor to the output side. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.
