ABSTRACT:
A torque limiter having an inner cylinder, an outer cylinder rotatably mounted around the inner cylinder, a closure member mounted between the outer cylinder and the inner cylinder to close one end of the outer cylinder, a coil spring mounted between the inner cylinder and the outer cylinder and having one end coupled to the outer cylinder and the other end coupled to the closure member so as to be tightened against the outer peripheral surface of the inner cylinder. The outer peripheral surface of the inner cylinder has a roughness Ra (arithmetical mean deviation) of 0.6-1.0, and the coil spring is formed of a wire having a circular cross-section.
