摘要： A decoupler is provided that includes a pulley around which a belt is wound. A sprag limiter is fixed to an interior circumference of the pulley and has protrusions formed at predetermined intervals in a circumferential direction on an interior circumference thereof. A sprag hub is disposed in the sprag limiter and has first apertures formed at predetermined intervals from an interior circumference to an exterior circumference thereof. A shaft hub is disposed in the sprag hub and has second apertures that are formed to correspond to the first apertures from an interior circumference to an exterior circumference thereof. Sprags having lower end portions are each inserted into the second apertures, central portions are each inserted into the first apertures, and upper end portions are in contact with the interior circumference of the sprag limiter, and allow the shaft hub to rotate in one direction based on the pulley movement.
