A muffling structure of a high-speed ball screw is composed of a holder, a screw, at least one pair of corresponding rollers, seal rings and a sleeve. The holder has a central through hole which is provided with threads. At least one pair of hollowed out set-in grooves are correspondingly provided on the holder such that the roller rings can be inserted along the hollowed out set-in grooves into the interior hole of the holder, and that at least one pair of the disposed roller rings can totally cover the periphery of the screw, thereby the roller rings will become an oval shape to allow the steel balls to roll smoothly without any obstacle and to obtain a muffling effect over the high-speed rotating ball screw.
