In a vehicle, an amount of change of a turning angle of a turning mechanism to an amount of change of a steering angle of a steering input device is defined as a transfer ratio, the turning mechanism is rotationally driven by a turning drive unit, and a driver's body posture parameter is detected by a body posture parameter detector. An apparatus for steering the vehicle includes a controller that executes an automatic steering mode that determines a target value for the turning angle of the turning mechanism based on a travelling condition of the vehicle and/or information about a road on which the vehicle is travelling, and controls the turning mechanism to adjust the turning angle of the turning mechanism to the target value. A transfer ratio adjuster adjusts the transfer ratio in accordance with the body posture parameter during execution of the automatic steering mode.
