ABSTRACT:
A webbing retractor includes a base, a take-up spindle supported rotatably on the base, a ratchet wheel mounted on the take-up spindle, a pawl engageable with the ratchet wheel, and a means supporting the pawl on the base. The supporting means includes a pawl pin having a large-diameter portion and small-diameter portion, a hole receiving the small-diameter portion of the pawl pin, a means for preventing the pawl pin from slipping off from the hole, and a bulged part pressed out in the direction of the thickness of the base. The bulged part has outer wall defining the hole and extending substantially in parallel to the base and a shoulder portion extending between the base and outer wall. The large-diameter portion of the pawl pin is arranged within the bulged part.
