A grill assembly for a cyclone dust collecting apparatus for use in a vacuum cleaner capable of improving dust collection of the vacuum cleaner by preventing dirt from flowing into a vacuum-generating device after passing through a grill. The grill assembly is disposed at an upper part of an air discharge passage of a cyclone body for separating dirt from a whirling air current by centrifugal force by forming the whirling air current from drawn air, and the grill assembly prevents dirt from being drawn into the vacuum-generating device of the vacuum cleaner. The grill assembly comprises a grill body having a plurality of passages formed thereon and filtering units disposed along an interior wall of the grill body for filtering dust drawn into the grill body through the plurality of passages.
