ABSTRACT:
In the seat belt retractor of the invention, the main pawl 17 turns into engagement with the teeth 23a of the lock ring 23, so that the rotational force of the reel shaft in the webbing unwinding direction is transmitted to the lock ring 23 to turn it in the same direction . This rotation of the lock ring 23 is transmitted to the clamp member 26 through the arm 24 to turn the clamp member 26. As a result, the webbing 3 is fastened between the clamp member 26 and the force-bearing member 27, so that the webbing 3 can be locked against further unwinding. This makes it possible to incorporate clamp means to even a frame lock type of seat belt retractor, and improves the reliability of part engagement much more.
