A grill assembly of a cyclone dust collecting apparatus for a vacuum cleaner capable of improving the capability of dust collecting of the vacuum cleaner by reducing the amount of the filth drawn into a vacuum generating device through a grill. The grill assembly, disposed at the upper part of the air discharging passage of a cyclone body that separates filth from a whirling air current by a centrifugal force for the whirling air current of the drawn air for preventing the filth from being drawn into the vacuum generating device of the vacuum cleaner, includes a grill body and a plurality of passages disposed therein. The extended line of the center line of the passages forms an acute angle with a stream line of the whirling air current.
