A cyclone dust collecting apparatus of a vacuum cleaner has: a cylindric-type cyclone body for centrifugally separating an air drawn into from an outside through a suction pipe and discharging a clean air through a discharge pipe; a dust collector disposed at a lower part of the cyclone body in order to collect a dust centrifugally separated from the air; and a plurality of dust backflow and rotation prevention members protruded from a bottom of the dust collector for a predetermined length in order to prevent the dust collected at the bottom of the dust collector from being flown. According to the cyclone dust collecting apparatus of the vacuum cleaner having the above construction, the flow of the dust collected at the bottom of the dust collector is prevented, and the dust is not discharged through the discharge pipe, thus the dust collection efficiency of the cyclone dust collecting apparatus is improved.
