An electric power steering apparatus includes: a pinion shaft connected to a steering shaft coupled to a steering wheel, the pinion shaft being configured to transmit an operation of the steering wheel by a driver; a rack bar elongated along a lateral direction of a vehicle, having a first screw recess defined with a predetermined length in a portion of an outer circumferential surface of the rack bar, and including, on one side, a rack gear coupled to and interlocked with the pinion shaft; a motor configured to generate a steering assist power in proportion to a steering torque applied to the steering wheel; and a roller screw unit rotatably engaged with and coupled to the first screw recess to transmit the steering assist power generated from the motor to the rack bar.
