ABSTRACT:
In a seat belt retractor, cross-section of a reel shaft 4 is formed in octagonal cylinder, and each side of the octagon, i.e. outer peripheral surfaces 4b between corners 4a of the reel shaft 4 are formed in inwardly curved depression. Therefore, when a webbing 3 is taken up on the reel shaft 4, the webbing 3 is brought into contact only with the corners 4a of outer peripheral surfaces of the reel 4, and high compressive force f is intensively applied on the webbing 3 at the corners 4a of the reel shaft 4. As the result, high friction force is generated between the corners 4a and the webbing 3 and between the webbing coils at the corners 4a, and this prevents the pulling-out of the webbing 3. Thus, the pulling-out of the webbing due to tightening phenomenon can be prevented in reliable and satisfactory manner.
