PROBLEM TO BE SOLVED: To provide a vacuum cleaner silencer capable of significantly reducing the noise generated when the vacuum cleaner is used. SOLUTION: The vacuum cleaner silencer has at least one silencing partition board attached inside an exhaust passage. Small holes are disposed on the silencing partition board, and the silencing partition board is attached in the direction perpendicular to the air current flowing inside the exhaust passage. Accordingly, the noise generated when the vacuum cleaner is used can be significantly reduced. COPYRIGHT: (C)2005,JPO&NCIPI
