<P>PROBLEM TO BE SOLVED: To provide a ceiling fan that can maintain airtightness between a high pressure air generating part and a connection duct and improves packaging performance. <P>SOLUTION: The ceiling can has a sealing means for maintaining airtightness between the high pressure air generating part 8 and the connecting duct 11. The sealing means 14 is configured by a rib shape flange part 17 protruding in a circumferential direction with respect to an opening from an opening part 16 of the high pressure air generating part 8, and a groove part 19 formed on an inner surface of the opening part 18 of the connection duct 11. In the flange part 17, a surface facing the high pressure air generating part 8 is tapered. In the groove part 19, a surface of an end side of the connection duct 11 is tapered. The flange part 17 and the groove part 19 are configured to press each other by a load applied to the sealing means 14 through an empty weight of the connecting duct 11 and an airflow blow-out part 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
