Abstract
In a hydraulic supply apparatus, one or more fitting grooves are formed along the outer circumferential surface of a ball nut, and corresponding fitting protrusions are formed on the inner circumferential surface of a damper coupled to the ball nut. This configuration minimizes damper movement, thereby reducing vibration and noise caused by collision with a bushing member during axial movement of the ball nut.
