<p>PURPOSE:To readily limit the transmitting torque to an output shaft by providing a clutch mechanism between a casing of a motor drive device and a motor which is rotatably supported. CONSTITUTION:When a switch knob 54 is pushed so that a microswitch 28 is turned ON, a motor 12 used for a geared motor 12 rotates to rotate an output shaft 18. When a load torque which is applied to the shaft 18 increases, a slide occurs between a retainer plate 64 and a facing 62, and the motor 12 itself rotates. As a result, a transmitting torque which is transmitted from the motor 12 to the shaft 18 is limited.</p> |
