An apparatus for the steering power of a vehicle is provided to employ a plurality of motors and planet gears, thereby coping with changing a steering direction through the easy control of a steering force. An apparatus for the steering power of a vehicle includes a steering axis(10), at least one planet gear(80), a ring gear(70), the first worm(40), the first motor(20), a carrier(90), the second worm(50), and the second motor(50). The planet gear(80) makes contact with the steering axis(10) along the circumference of the steering axis(10). The ring gear(70) makes contact with each planet gear(80) along the inner circumference of the steering axis(10). The first worm(40) makes contact with the outer surface of the ring gear(70). The first motor(20) delivers power to the first worm(40) through the first clutch. The carrier(90) is in contact with the outer surface of the steering axis(10) in an inner space. The second worm(50) is in contact with the outer surface of the carrier(90). The second motor(30) delivers power to the second worm(30) through the second clutch.
