Abstract
If a V-gear abruptly rotates in a pulled-out direction due to reaction generated by rotation in a take-up direction being stopped when rotating in a take-up direction, a restriction body restricts swinging of a W-pawl in operation direction, so that lock of pulling-out of a webbing from a spool is suppressed. An insertion portion of a frictional spring of the restriction body is caught by an abut portion and a catching portion of a support hole. At an opening-side portion of the support hole, an enlarged portion is formed such that a position other than a position of the catching portion at the opening-side portion is enlarged compared to that of the catching portion. Even if the minimum-diameter of the support hole is small, strength of a molding portion for the support hole in a mold for the V-gear can be improved and lifetime thereof can be longer.
