Abstract
In a spring type torque limiter, it is proposed to prevent cut end portions of a coil spring fitted on an inner ring from causing chatter of the torque limiter, even if the cut end portions of the coil spring are separated from a radially outer surface of the inner ring in order to prevent burrs remaining on the cut end portions of the coil spring from contacting the radially outer surface of the inner ring. The first cut end portion of the coil spring fitted on the inner ring is inserted in a recess of a first spring receiving protrusion formed on the radially inner surface of the outer annular member. The second cut end portion is inserted in a recess of a second spring receiving protrusion formed on the inner surface of the lid member, thereby restraining the first and second cut end portions with the recesses.
