ABSTRACT:
A retractor for use with a seat belt is capable of releasing a state of end lock without using a complicated structure of a locking mechanism for operating the locking of the retractor in the case of an emergency of a vehicle. The retractor contains an angular engaging surface at one end of a winding shaft, that engages with a retractor base at certain portions. The angular engaging surface has a groove in the direction of a circumference of the winding shaft into which the portions may be engaged. This groove helps to prevent the displacement of the winding shaft in the direction of thrust and allows for superior locking.
