PROBLEM TO BE SOLVED: To provide a torque limiter for securing sufficient strength to so-called reverse torque while preventing an increase in the radial size. SOLUTION: An outer ring body has a slit into which a hook portion of a coil spring is locked and which has an opening side abutting face and a locking side abutting face for abutting on the hook portion when rotating torque on the opening side and the locking side operates, and a locking side protruded portion which extends from the locking side abutting face inward in the radial direction and which has a locking side extending face for abutting on the hook portion together with the locking side abutting face when rotating torque on the locking side operates.
