Abstract
A steering apparatus includes a first reducer having 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 having 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. The steering apparatus is capable of reducing the fluctuation range of torque ripple in using a double motor and double reducer structure, thereby relieving a fatigue and discomfort of a driver.
