ABSTRACT:
In a seat belt retractor according to the present invention, an arcuate fall preventing flange 4m is provided on an outer surface of a guide flange 4b of the reel shaft. The central axis a.sub.2 of the reel shaft 4 is eccentrically shifted from the central axis a.sub.1 of the through-hole 2d of the right-hand side wall 2a by an eccentric amount "b" and the reel shaft is faced to the through-hole 2d to coincide the peripheral edge of the profile consisting of the left-hand guide flange 4c and the fall preventing flange 4r with the through-hole 2d. In this state, the reel shaft is passed through the through-hole 2d. After that, the reel shaft is moved upward to align the central axis a.sub.2 of the reel shaft 4 with the central axis a.sub.1 of the through-hole 2d of the right-hand side wall 2a. Thereby, the reel shaft 4 is assembled in the predetermined position of the frame. In this state, the fall preventing projection 4m is positioned so that the fall preventing flange 4m abuts on the teeth 2f to prevent the reel shaft from coming off.
