In a microwave oven in which a motor rotates a turntable through a coupling detachably mounted on the outer bottom center of the turntable, a motor-fixing structure comprises a cylindrical bearing for covering the power transmission shaft around the portion near the motor in such a manner as to allow the shaft to be rotatable and to permit the coupling to be mounted on the shaft end. Threads are formed on the outer circumferential surface of the bearing and a through-hole is provided for insertion of the bearing into the oven. The through-hole is formed in the microwave oven bottom wall in the area facing the coupling mounting position and a nut is provided with top and bottom faces. Each of these faces are larger than the opening of the through-hole and the nut is made engaged with the threads of the bearing inserted through the through-ho;e and projecting into the oven, thereby fixing the motor. |
