PROBLEM TO BE SOLVED: To provide an outer rotor type blower capable of preventing deterioration of impeller efficiency by straightening the change of wind velocity from a blade inlet to a blade outlet. SOLUTION: In a sirocco fan 14 of an outer rotor type blower 10, the change in a distance from an inner periphery side to an outer periphery side between respective blades is straightened to make the change of wind velocity linear, thereby improving impeller efficiency.
