PROBLEM TO BE SOLVED: To provide a dry cleaning body capable of attaining an assist effect by a compressed air flow and contributing to improving cleaner performance including elimination of visco-elastic contaminations.SOLUTION: If an opening portion 18 of a dry cleaning body 50 abuts on and closes a cleaning target 20 in a state in which vacuum means (not shown) is activated, outside air flows into the dry cleaning body 50 from an inlet 24 with high speed to generate a revolving air flow 30. A nozzle hole 62a serving as an air flow injection port is provided on an outermost circumferential side of the revolving air flow 30, and compressed air flow CF is injected generally parallel to the revolving air flow 30. The revolving air flow 30 is accelerated by the compressed air flow CF and a flight speed of a cleaning medium 5 increases, accordingly, thereby increasing the number of times of striking and circulation flight by which the cleaning medium 5 strikes against the cleaning target 20. |
