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 of a cyclone dust collecting apparatus for a vacuum cleaner is disposed at an upper part of an air discharging passage of a cyclone body that generates whirling air current from the air drawn thereinto and separates filth from the drawn air by a centrifugal force of the whirling air current. The grill assembly for preventing the filth from being drawn into a vacuum-generating device of the vacuum cleaner comprises a grill body, and a plurality of blades formed at a predetermined space for forming a passage along an outer circumference of the grill body. The passage is at an acute angle with a stream-line of the whirling air current, and each blade includes a protrusion member protruding from the outer circumference of the grill body to the outer part. |
