ABSTRACT:
A microwave oven including a rotary table or turn table disposed on the bottom surface of a heating cavity and a rotary member associated with a driving motor through a driving mechanism and disposed adjacent to the rotary table and the bottom wall of the heating cavity for rotating the rotary table through magnetic coupling means. Should the rotary table be prevented from being rotated or locked for some reason, the magnetic coupling is released, so that damage to the driving motor and the like are advantageously prevented.
