Zusammenfassung:PROBLEM TO BE SOLVED: To improve sealing performance when an air suction port is closed. SOLUTION: A blower 14 is disposed on the air-flow downstream side of the two air suction ports 12, 13. A plate door 18 for opening/closing the two air suction ports 12, 13 is disposed on the air-flow upstream side of the two air suction ports 12, 13. On the marginal portions of the two air suction ports 12, 13 in a case 11, two suction port sealing surfaces 24, 25 are formed on which a plate surface on the air-flow downstream side of the plate door 18 abuts. A correlation between the arrangements of the two air suction ports 12, 13 is configured so that the one air suction port is closed with the other air suction port opened by the plate door 18, and negative pressure is generated in the one air suction port when air is sucked through the other air suction port by the blower 14. The plate door 18 is pulled toward the side of the one air suction port by the negative pressure. COPYRIGHT: (C)2010,JPO&INPIT
