The steer-by-wire steering system comprise a steering input device and a steering operation device that steers wheels which are mechanically coupleable. The steering input device includes a steering-side motor that supplies a steering shaft with a steering reaction force, the steering operation device includes a steered-side motor that supplies a rack shaft with a steering force, and a power supply control circuit that controls the steering-side motor to generate the steering reaction force and that controls the steered-side motor to generate the steering force. When the duty ratio of a duty signal that is generated to control the power supply to the steered-side motor reaches a setting value that is defined to indicate that a steered angle becomes unable to follow a steering angle, the power supply control circuit controls the power supply to the steering-side motor such that the steering-side motor increases the steering reaction force.
