Abstract
A seat belt retractor having a reel shaft that performs relative rotation in the unwinding direction, where teeth of a main pawl approach teeth of a side wall of the seat belt retractor by a set amount, but the teeth of the main pawl do not approach the teeth of the side wall any further. When the reel shaft further rotates in the unwinding direction, a tooth of the main pawl comes into contact with the steep slope of a tooth of the side wall. Thus, the main pawl reaches a standby position. When the reel shaft further rotates in the unwinding direction, the tip of the tooth of the main pawl is guided toward the bottom tooth of the side wall by the steep slope of the tooth of the side wall, so that the teeth of the main pawl completely engage with the teeth of the side wall. Thus, the main pawl reaches a lock position or, in other words, the main pawl performs a self-lock action.
