The utility model provides a dust collector and a vacuum cleaner. Both the dust collector and the vacuum cleaner comprise a cylindrical container and a cyclone F is generated in the cylindrical container for the centrifugal separation of air containing dusts. Meanwhile, separated dusts are gathered. The density of temporarily accumulated dusts is increased so as to collect dusts as much as possible. The dust backflow is prevented so as to reliably collect dusts. The dust collector 7 comprises cylindrical container 35 equipped with a bottom, a partition wall 39 for separating a suction tube 36 from an exhaust pipe 37, a filter part 41 equipped with an opening 39a and in a cylindrical shape roughly concentric with the cylindrical container 35, and a cup-shaped member 42. The cup-shaped member 42 is arranged closer to the rest bottom part 35b of the cylindrical container 35 than the filter part 41. Gaps 51 and 52 are formed between a sidewall 53 and the inner peripheral surface of the cylindrical container 35, and between the sidewall 53 and the rest bottom part 35b of the cylindrical container 35. A bottom wall 54 equipped with an opening 54a is also provided and a filter part 45 is arranged in the opening 54a of the bottom wall 54. |
