PURPOSE: A microwave oven is provided to achieve improved productivity and reduce manufacturing costs by allowing for ease of repair and replacement of the magnetron mounted in the electrical component chamber. CONSTITUTION: A microwave oven comprises a cooking tray(25) mounted to be rotatable in a cavity; a drive motor arranged in the lower portion of the cavity so as to rotate the cooking tray; and a coupler(30) interposed between a rotating shaft(26a) of the drive motor and the cooking tray in such a manner that the coupler allows for transmission of the rotating force of the drive motor to the cooking tray. The coupler includes an upper coupler(31) coupled with the cooking tray; and a lower coupler(32) having an upper portion coupled with the upper coupler in such a manner that the coupler has an adjustable height, and a lower portion coupled with the rotating shaft of the drive motor.
