PROBLEM TO BE SOLVED: To suppress size increase of a spool.SOLUTION: A webbing winding device 10 comprises: a spool 14 to which a webbing 12 is wound, and having a webbing insertion hole 14B into which the webbing 12 is inserted; and a stopper member 15 engaged to a peripheral edge part of the webbing insertion hole 14B, thereby fixing an end of the webbing 12 to the spool 14. The webbing winding device 10 further comprises load support parts (a portion P2 on one side of an axial direction of a first serration part 34A formed on a torsion shaft 34, and a portion P5 of the other side of the axial direction of a columnar part 34E), which are arranged on inside of the spool 14 in the radial direction, with respect to the stopper member 15, arranged to be proximate to the spool 14, and support a load which is input to the spool 14 from the webbing 12 via the stopper member 15.SELECTED DRAWING: Figure 4 |
