Abstract
A cross flow fan of an air conditioner for reducing noise and vibration produced due to a rotation of the cross flow fan, by an improvement in a blade arrangement which has a regularity as a whole and an irregularity as respective units. Such a cross flow fan is installed in an indoor unit of the air conditioner, and has a plurality of blades functioning to circulate an inside air. The blades of the cross flow fan are divided into a plurality of blade groups consisting of a uniform number of blades, and the blades in the same blade group are arranged at uniformly increasing angles, while the pattern of the blade arrangement throughout the complete blade groups is uniformly formed.
