A vehicle steering apparatus utilizing SBW capable of downsizing an expensive turning-power motor, in which a steering mechanismprovided with a steering wheelmaneuvered by a driver is mechanically separated from a turning mechanismfor turning road wheels. A turning-power motorof the turning mechanismturns the road wheelsbased on a turning angle-steering angle ratio determined by a control portionof a controllerin accordance with a vehicle speed of the vehicle. The turning angle-steering angle ratio increases with increasing vehicle speed until the vehicle speed reaches a predetermined value from zero; while when the vehicle speed is higher than the predetermined value, the turning angle-steering angle ratio decreases with increasing vehicle speed.
