Abstract
The seat belt retractor of the present invention is provided with a fragile portion .gamma. near a supporting section of a rotating shaft 21 on two side walls 2b (and 2a--not shown) of a case 2. The fragile portion .gamma. undergoes plastic deformation or rupture when a load exceeding a predetermined value is applied on a seat belt 1 through the rotating-squeezing member 20 and a rotating shaft 21 by pulling force. When the fragile portion .gamma. undergoes plastic deformation or rupture, the rotating-squeezing member 20 is moved toward loading direction, and the rotating-squeezing member 20 is separated from the sliding-squeezing member 19. Then, the rotating-squeezing member 20 is turned over, and the squeezing force on the seat belt 1 by the rotating-squeezing member 20 and the sliding-squeezing member 19 is alleviated. As the result, the application of highly concentrated load on the seat belt can be avoided.
