1. A steering apparatus comprising:
a first reducer comprising a first worm coupled to a first motor and a first worm wheel which rotates by being meshed with the first worm;
a second reducer comprising a second worm coupled to a second motor and a second worm wheel which rotates by being meshed with the second worm; and
a screw shaft on which the first reducer is mounted on one side and the second reducer is mounted on the other side,
wherein an angle at which the first reducer and the second reducer are mounted to the screw shaft is set to an offset angle, and
wherein the offset angle represents a degree of angle at which a center of a tooth provided in the first worm wheel does not coincide with a center of the corresponding tooth provided in the second worm wheel, so that the first worm wheel and the second worm wheel do not simultaneously mesh with the first worm and the second worm, respectively.
