PURPOSE: A rotary fan is provided to maximize the reliability in use by making air-blowing vanes blow to all directions while air-blowing vanes are rotating at an angle of 360 degrees. CONSTITUTION: A rotary fan comprises a lower terminal(30) fixed at the bottom of a lower body(20), an upper terminal(40) fixed to a driving motor(M1) installed at the bottom of a rotary disk(50), to be able to rotate while licensing power, a motor shaft(M2-1) of a rotary motor(M2) fixed to the middle of an upper cover(10) for control of rotating, and a motor bracket(60) installed to the outside of the rotary motor(M2). Both ends of a hexagonal pipe(70) to the inside of a supporting bracket(65) and a cover pipe(80) to the outside of a supporting are inserted to be simultaneously rotated by rotating of the rotary motor(M2). The hexagonal pipe forms holes for inserting the shafts and a first, second, and third shaft(91,92,93) is inserted in the holes. A first, second, and third air-blowing vanes is installed to the front ends of the first, second, and the third shaft. A driving pulley(51) is installed to the front end of the motor shaft(M1-1) of the driving motor installed at the bottom of the rotary disk. The simultaneous rotating of the rotary fan is performed through interlocking of the belt interlocked to the driving pulley.
