PROBLEM TO BE SOLVED: To provide a cyclone dust-collecting apparatus which reduces noises. SOLUTION: The cyclone dust-collecting apparatus is equipped with a cyclone enclosure where a suction passage is formed, an upper cover disposed on the upper part of the cyclone enclosure, a dirt receptacle disposed under the cyclone enclosure, and a nose reducing member disposed to enclose an inner surface of a side wall of the cyclone enclosure. The air flowing through the suction passage collides with the noise reducing member, and the noise is reduced. COPYRIGHT: (C)2006,JPO&NCIPI
