PCT No. PCT/JP91/00844 Sec. 371 Date Jan. 23, 1992 Sec. 102(e) Date Jan. 23, 1992 PCT Filed Jun. 21, 1991 PCT Pub. No. WO92/00210 PCT Pub. Date Jan. 9, 1992.A seat belt retractor is formed of a frame having a pair of opposite side walls and a rear wall, a seat belt take-up reel situated between the side walls, a first gripping member mounted on the rear wall, a shaft extending between the side walls, a second gripping member rotationally disposed over the shaft, and a lock actuating device to move the second gripping member. The second gripping member includes a support hole at one side and a pusher at the opposite side, and can rotate to hold a seat belt between the pusher and the first gripping member. A sleeve made of synthetic resin is attached to the second gripping member such that a cylindrical portion is located inside the support hole and a flange projects outwardly from an outer surface of the second gripping member. When a predetermined acceleration of the vehicle is not detected, the second gripping member does not directly contact the shaft and the frame by the sleeve to reduce noise. When the predetermined acceleration is detected, the sleeve may deform to allow the second gripping member to directly contact the shaft. Thus, the seat belt is securely retained between the first gripping member and the pusher.
