In the twin stirrer fan installed on an upper plate of a cavity of a microwave oven to distribute microwave, a pair of rotating axes are vertically installed on a bottom of the stirrer fan cover (120) made of high frequency energy permeable material, a pair of fan holder (110 and 111) where a plurality of wings are radially and vertically installed in a circle by high frequency energy permeable material are respectively inserted in the rotating axes (122 and 124), thereby being capable of rotating by the wind which flows in, stirrer fans (100 and 101) reflecting high frequency energy on an upper surface of a pair of fan holders (110 and 111) are installed to rotate with respective fan holders (110 and 111), the stirrer fan cover (120) where a pair of fan holders (110 and 111) and a pair of stirrer fans (100 and 101) are rotatablely installed is provided with the wind through a suction port formed on one side wall of the cavity, and it is fixedly installed on an upper plate of the cavity so that the high frequency energy may be provided from the upper part thereof to be diffusedly reflected.
