Abstract
A seat belt retractor includes a base frame, a spool having a spool shaft journalled to the base frame, a webbing wound around the spool, a return spring connected to the spool for winding the webbing by a return force thereof, a motor connected to the spool for winding the spool, and a speed-reduction mechanism interposed between the motor and the spool. The speed-reduction mechanism winds the webbing at a low speed for fitting the webbing to an occupant, and includes a contrate gear with a predetermined reduction gear ratio. Thus, the webbing is wound by operation of the motor via the contrate gear.
