A steering apparatus for a steer-by-were system includes a driving member rotating in conjunction with a steering wheel and having a first stopper protruding from the driving member; a change gear receiving rotational force from the driving member, changing a rotational speed, and outputting a changed rotational speed; and a driven member receiving the rotational force output from the change gear, rotating at a rotational speed different from that of the driving member, and having a second stopper, which protrudes from the driven member, disposed within a rotation radius of the first stopper. The second stopper comes into contact with the first stopper at a predetermined steering angle during rotation of the driving member.
