Abstract
To allow a seat belt retractor to be easily assembled and to be made compact while effectively operating a pretensioner and an energy absorbing mechanism. A plurality of ballsrotate a ring gearby gas generated in the event of an emergency. Since internal teethare meshed with external teeth, a pinionis rotated by the rotation of the ring gear, and a spool retracts a seat belt. After pressing the ring gear, the ballsseparate from the ring gearand are stored in an arc-shaped passage. Since the seat belt is then withdrawn, the pinionand the ring gearrotate in a seat-belt withdrawing direction. In this case, some of the ballsin contact with the ring gearare returned by the ring gear. Therefore, the ring gearmore smoothly rotates because the influence of the ballsis suppressed.
