<p>A clutch type torque control device characterized in that balls seated in ball receiving holes made in a main shaft are pressed against squarely planed-off surfaces made at the outer circumferential surface of a cam fitted to a driving shaft which is driven by an air driven motor through the medium of a spring and a cam ring for transmission of motive power from the cam to the main shaft and a stop pin inserted in the main shaft is engaged with a planed-off part made at the outer circumferential surface of a pilot pin slidably inserted in the cam, whereby when a torque load on the main shaft reaches a predetermined torque value the stop pin is disengaged from said planed-off part due to rotational difference between the cam and the main shaft and consequently a valve kept open through the medium of the pilot pin and a push rod is closed, resulting in the stopping of the motor.</p> |
