<P>PROBLEM TO BE SOLVED: To obtain a crossflow fan capable of lowering ventilation resistance in a flow path between blades and an air conditioner including the same. <P>SOLUTION: In the crossflow fan 8 equipped with an impeller 8a having at least two rings 8b arranged at intervals in the direction of a rotational axis O of the fan, and a plurality of blades 20 arranged at intervals in the circumferential direction of the rings 8b between the rings 8b, the blades 20 are divided into a plurality of regions in the direction of the rotational axis O of the fan. Both end portions adjacent to the rings 8b are taken as blade ring vicinity parts 20a, central portions of the blades 20 are taken as blade-ring-interval central parts 20b, and a blade inner circumferential end part 20c being the inner circumference end of the blade 20 at the impeller 8a side is formed to be thinner at the blade-ring-interval central part 20b than at the blade ring vicinity part 20a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
