PROBLEM TO BE SOLVED: To provide a turbofan capable of stabilizing quality while improving productivity. SOLUTION: In the turbofan 1, a blade 6 and a suction ring 7 are connected by a fitting part 8 and a receiving part A. By providing a notch 9 to the fitting part 8 of the blade 6, the suction ring 7 can be easily mounted in the blade 6 up to a certain extent even if the fitting part 8 and the rib 10 are not in parallel. The stress of the fitting part 8 and the rib 10 can be also eased. Since the induction part 14 is provided to the blade side of the rib 10 in the suction ring 7, the suction ring 7 can be easily mounted in the blade 6. The stress onto the base 13 of the fitting part 8 and the base 12 of the rib 10 can be reduced, thereby obtaining the turbofan capable of stabilizing quality while improving productivity.
