いない。(Prior art) and (Problem to be solved by the invention)
In variable rotor blade axial flow fans that handle high-temperature gas, air is introduced into the fan to cool the inside of the rotor, prevent dust from entering the rotor, and prevent the rotor from sticking. Although the air is discharged into the air, the air is not concentratedly discharged to the blade root, where the rotor blades are most likely to stick.

中のダストが堆積し、動翼スティックの要因となってい
る。For this reason, dust in the gas accumulates at the roots of the rotor blades, that is, in the gap between the rotor blades and the wheel, which causes the rotor blades to stick.
