Abstract: In a steering device, the transmission ratio variable mechanism changes a transmission ratio. The transmission ratio is a ratio of the turning angle of a wheel to the steering angle of a steering wheel. In the stationary-steering mode, the ECU sets a low transmission-ratio state where the transmission ratio is reduced compared with the transmission ratio in an ordinary mode when the steering wheel is increasingly steered while setting a zero-transmission-ratio state where coupling between the steering wheel and the wheel is released to set the transmission ratio to zero when the steering wheel is returned.
