Disclosed is an active steering system which includes a ring gear which has an engagement hole with gear teeth on the inner peripheral surface thereof; a harmonic gear which is eccentrically inserted into the engagement hole of the ring gear, engages with the ring gear, and has a plurality of penetrated guide holes; a plurality of guide shafts which are inserted into the guide holes of the harmonic gear and guides the eccentric rotational movement of the harmonic gear; and bearings which are mounted on the guide shafts and reduce friction between the guide shafts and the guide holes. The active steering system reduces power loss and operation noise when the harmonic gear eccentrically rotates. |
