ABSTRACT:
A retractor for a seat belt includes a retractor base, a bobbin fixed to a winding shaft rotatably supported to the retractor base for winding a webbing, and a webbing guide having a first positioning portion located on the side of the bobbin and a second positioning portion located on the side of the upper end of the retractor base. The webbing guide is fixed to the retractor base for regulating a webbing moving path so that the webbing wound around the bobbin is drawn out from a prescribed position on said retractor base. The first and second positioning portions each has a protrusion portion provided with a plurality of protrusions abutting on the surface of said webbing and the surface of each protrusion abutting on said webbing forms a smooth bending face. The retractor provides a small change in the contact resistance between the webbing and the webbing guide positioning the webbing in a retractor base and can maintain smoothness of the draw-out and winding operations of the webbing, so that it is effective to improve the reliability of the draw-out and winding operations in the retractor and also general versatility of the retractor.
