Abstract
A pretensioner of a seatbelt retractor adapts a load limiter to take at least two safety countermeasures upon the impact of a vehicle. A clutch includes a circular groove portion formed around the periphery thereof to allow a predetermined length of the cable to be wound thereon. A plurality of second coupling projectors each have a right-angled surface toward one direction and a slanted surface toward the other direction adjacent to the periphery of one side surface thereof. At least three coupling groove portions cut out at one side in a right-angle and at the other side in a slant angle and a fixing groove formed to fix the other end of a cable and upper and lower stoppers respectively and integrally formed in a diametric line on the upper and lower portions of the circumference thereof.
