ABSTRACT:
In a retractor wherein webbing is drawn out from a take-up spool and extends partially around a drum, a locking device for the webbing for the seat belt is provided with a sensor for sensing sudden acceleration or deceleration exerted on a vehicle body. A first restraining pawl is moved by the sensor to a position preventing rotation of the spool. A second restraining pawl is driven by a tilting member to prevent rotation of the drum, and a frictional restraining member for pressing the webbing is provided on the base of the drum in a position opposed to a fixed frictional restraining member provided on the base of the retainer.
