PROBLEM TO BE SOLVED: To reduce noise as well as increasing fan air capacity by forming a structure of a fan motor arranging part of a blower such as a fixing indoor unit of an air conditioner for arranging on a ceiling, with a good heat radiating performance and in a compact size as much as possible. SOLUTION: This device comprises a hub 9, multiple air blowing blades 8a disposed at prescribed clearances in one side surface side circumferential direction of an outer peripheral part 9b of the hub 9, a fan motor 23 for rotating the multiple air blowing blades 8a through the hub 9, and an attaching part 2a to which an impeller 8 composed of the hub 9 and the multiple air blowing blades 8a through the fan motor 23 is attached. A central part 9a not having the air blowing blades 8a of the hub 9 is formed in a cylindrical shape, the fan motor 23 of an outer rotor type is built in its inside, and is integrated with each other. The impeller 8 is attached to the attaching part 2a through a rotary shaft 26 of the fan motor 23 and the bearing member 28, and heat radiating fins 25a, 25b, 35 are disposed on an air blowing passage surface side of the cylindrical hub central part 9a. |
