ABSTRACT:
A spring-loaded torque limiter includes an annular outer member, an inner ring rotatably inserted in the annular outer member, a coil spring fitted on the radially outer surface of the inner ring, and a lid member fitted between the inner ring and the annular outer member, thereby closing a gap therebetween at one end of the annular outer member. The coil spring has a uniform diameter. The annular outer member has an axially inner end face formed with a protrusion adapted to engage one of the two end faces of the coil spring. The lid member has an axially inner surface formed with a protrusion adapted to engage the other end face of the coil spring.
