<p>PURPOSE:To provide an inexpensive torque limitter which can stably operate for a long period, and a paper feeding device with the limitter. CONSTITUTION:A sensor spring 8 which is engaged with a rotary driven cylinder 3 and a reverse revolution roller case 6 is deflected when the high load torque over limit torque is applied, and the angle formed by the rotary driven cylinder 3 and the reverse revolution roller case 6 varies, and also the relative angle between the reverse revolution roller case 6 and a stop collar 5 varies, and a clutch spring 4 is deflected, and the transmission of the turning power from a rotary driving cylinder 1 to the clutch spring 4 is cut off.</p> |
