Provided is a steering system that includes a mechanical mechanism having a simple structure and secured safety and is capable of controlling angles of left and right front wheels in accordance with a vehicle velocity and a steering command angle so as to improve responsiveness of a vehicle to an operation of a steering wheel and/or a steering command from an automatic drive device. The steering system (100) includes: a first steering device (11) configured to steer left and right wheels (9) in a mechanically associated way by changing an angle of left and right chassis frame components (6); and a second steering device (150) configured to drive a supplementary turning actuator (5) to change angles of the wheels (9) relative to the chassis frame components (6). The second steering device (150) includes a supplementary turning control section (151) configured to perform a control to cause turning by a steering angle that is a difference between a steering angle determined by a numerical model of vehicle motion on the basis of the steering command angle and the vehicle velocity and an actual steering angle.
