A cable steering system is provided in which first control means controls the operation of a power steering motor disposed between Bowden cables and wheels based on a steering torque detected by a steering torque detection means disposed between a steering wheel and the Bowden cables, and a second control means controls the operation of a steering reaction force addition motor that applies a steering reaction torque to the steering wheel. It is possible to prevent deterioration of the steering feel by generating a steering reaction torque by the steering reaction force addition motor so as to compensate for a change in the steering torque while regulating the change in steering responsiveness due to expansion and contraction of the Bowden cables by generating an assist torque by the power steering motor so as to change the steering torque.
