Abstract
Rollers are opposingly disposed at a drawing-out port for a seat belt webbing which is drawn out from a retractor. When an impact load has occurred, both the rollers are turned to tightly hold the seat webbing therebetween. Thus, a surplus length which is ascribable to the elongation and tight winding of the webbing is prevented from being drawn out.
