Abstract
A spool 20 and a locking base 40 are connected through a torsion bar 70. A stop gear 82 and a positioning member 86 are engaged through threads with the male thread 42c of a locking base 40 so as to be separated from each other a predetermined distance. The locking base 40 and the torsion bar 70 are mounted to the spool 20 while the distance of separation between the stop gear 82 and the positioning member 86 is accurately set to a specified distance. When the tension of webbing increases due to the movement of a vehicle occupant in a vehicle collision and provides the torsion bar 70 with EA rotation while twisting the torsion bar 70, the stop gear 82 advances toward the positioning member 86 and comes into contact therewith.
