Abstract
A vacuum cleaner has a cyclone dust collector 4, arranged in a suction air passage, for separating dust by making sucked air into a whirling stream. The cyclone dust collector 4 has an inlet port 41a through which the sucked air is introduced, a dust collection chamber 41 for collecting separated dust, a lid 42 for opening and closing the dust collection chamber 41, an exhaust cylinder 44 through which the sucked air is discharged out of the dust collection chamber, and a shielding member 46 arranged below the exhaust cylinder 44. Dust is separated as a result of a whirling stream of air colliding with shielding ribs 46b and a circular portion 46a of the shielding member 46.
