1. A vehicle steering apparatus configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity, the vehicle steering apparatus comprising:
a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel;
a toe adjustment actuator coupled to the steered wheel; and
a controller configured to control a driving force of the toe adjustment actuator,
wherein the controller comprises:
a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector;
an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter; and
a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.
