<p>PROBLEM TO BE SOLVED: To provide a dry cleaning housing which can reduce or prevent contamination of a seal member due to an oil content or the like and can contribute to suppression of a labor and a cost increase after cleaning.SOLUTION: A bottom surface of a dry cleaning housing 50 is provided with a seal member 62 so that the seal member surrounds an opening 18. The seal member 62 is provided with a non-contact area 62a which does not contact a cleaning object surface 20 on the upstream side in a movement direction of a revolving air flow 30 in the opening 18. An intake flow channel 64 is formed between the non-contact area 62a and the cleaning object surface. When a suction device which is not shown in the drawings, is operated thereby creating a negative pressure in the housing, environmental air is flowed in so as to accelerate the revolving air flow 30 through the intake flow channel 64 due to an atmospheric pressure difference. Consequently, a contact area of the seal member 62 contacting the cleaning object surface can be reduced without lowering a cleaning function.</p> |
