Summary:Provided is a turbofan producing reduced noise and easily manufactured. A coupling portion 7 between a blade main portion 5 and a blade cover 6 is formed in a surface region (pressure surface 12) parallel to a direction of air flowing over the pressure surface 12 of each blade 2. With this configuration, the air sucked from a direction of a rotation axis of a turbofan 20 is less liable to enter a gap of the coupling portion 7 of the blade 2, thereby being capable of reducing noise. Further, noise is reduced so that high-precision dimensional control of the gap of the coupling portion 7 of the blade 2 is not required. Consequently, dimensional control at the time of manufacture is facilitated to thereby facilitate manufacture.
