<P>PROBLEM TO BE SOLVED: To improve assemblability of a torsion shaft in a spool. <P>SOLUTION: A webbing take-up device 10 has a sub torsion shaft 64 inserted into a spool 20 from one axial side of the spool 20 when assembled in the spool 20. Then the sub torsion shaft 64 is rotated in a take-up direction to stop the sub torsion shaft 64 from moving in the spool 20 in the take-up direction and toward one axial side. Further, a stopper 80 is fitted in an insertion groove 28 thereafter from the one axial side to stop the sub torsion shaft 64 from moving in the spool 20 in a drawing-out direction. The direction in which the sub torsion shaft 64 is assembled in the spool 20 is thereby limited to a direction parallel with the axial direction of the spool 20, so the assemblability of the sub torsion shaft 64 in the spool 20 can be improved. <P>COPYRIGHT: (C)2013,JPO&INPIT |
