Summary:PROBLEM TO BE SOLVED: To provide a vacuum cleaner which removes dust stuck in a filter by an outside air flow, surely stores the dust in a fine dust storage part without soaring thereafter, and keeps high suction force. SOLUTION: In the state of performing suction by an electric blower 2, outside air inflow is generated from an opening 20 into a dust collecting case 3, and fine dust 41 stuck to the filter 13 is removed by the outside air flow 50. Also, by providing dust soaring prevention means such as a dust soaring prevention rib A 17 and a dust soaring prevention rib B 22 in the fine duststorage part 16, for the problem that the removed fine dust 41 gets on the dust stir-up prevention means, is deposited and cannot be stored in the fine dust storage part in a conventional dust removing configuration not using the outside air flow 50, the fine dust is stored in the fine dust storage part 16 without soaring again by using the outside air flow 50. The vacuum cleaner whose suction force is not easily lowered, and which maintains high suction power for a long period of time and does not need maintenance for a long period of time further, is provided.
