ABSTRACT:
A torque limiter having an outer ring, an inner ring mounted in the outer ring and a shaft inserted in the inner ring. The outer ring is formed on the inner peripheral surface thereof with a plurality of tapered surfaces. Rollers are mounted between the tapered surfaces and a cylindrical outer peripheral surface of the inner ring. Torque setting springs are provided at one side of the rollers to urge the rollers toward a narrower side between the tapered surfaces and the cylindrical outer peripheral surface. A coil spring is mounted between the inner ring and the shaft so as to bind around the outer peripheral surface of the shaft and having one end thereof secured to the inner ring. The coil spring is mounted so as to be tightened when the shaft rotates in a direction opposite to the direction in which the torque setting springs urge the rollers.
