ABSTRACT:
A mechanism for driving a turntable in a heating apparatus uses a motor with the characteristic of reversing its direction of rotation when a load greater than its output torque is applied to its shaft. The shaft is engaged with a coupling member attached to the turntable but a gap is provided between the shaft and the coupling member such that they can rotate with respect to each other by a predetermined maximum idling angle before a power-communicating relationship is established between them. This maximum idling angle is set greater than the angle of rotation of the shaft necessary for the output torque of the motor to reach the starting torque of the coupling member.
