1. A reducer of an electric power steering apparatus, comprising:
a worm shaft bearing coupled to a worm shaft, which is tooth-engaged with a worm wheel, at an end of the worm shaft opposite to a motor shaft coupling portion; a bearing bush fitted on an outer circumference surface of the worm shaft bearing, and formed with a first through-hole at a worm wheel side and a second through-hole at a side opposite to the worm wheel side; a damping member fitted on the outer circumference surface of the bearing bush, the damping member having an inner circumference surface, on which a first support portion configured to pass through a first through-hole to support the outer circumference surface of the worm shaft bearing and a second support portion configured to pass through a second through-hole to support the outer circumference surface of the worm shaft bearing are formed, and an outer circumference surface supported on an inner surface of a gear housing; a cover member coupled to an end of the gear housing opposite to the motor shaft coupling portion; and a compression adjustment member coupled to the gear housing, and configured to compress the outer circumference surface of the worm shaft bearing so as to elastically support the worm shaft bearing toward the worm wheel so as to compensate for a clearance between the worm shaft and the worm wheel. |
