To suppress a temporal rise of a force limiter load.SOLUTION: A webbing winding device 10 is equipped with a spool 20 that can draw out and wind up a webbing 20A, and a rotator 50 that is disposed oppositely to the spool 20, and is prevented from rotating at emergency. The webbing winding device 10 is equipped with a wire 40 that has a base end portion 42 held, is disposed between the rotator 50 and the spool 20, and is wound around an inner rib 26 of the spool 20 when being deformed at emergency and the webbing 20A is drawn out, and an escaping portion 24B where a tip end portion 48 of the wire 40 escapes when the wire 40 is wound around an inner rib 26.SELECTED DRAWING: Figure 3 【課題】一時的なフォースリミッタ荷重の上昇を抑制する。【解決手段】ウェビング巻取装置１０は、ウェビング２０Ａを引き出し及び巻き取り可能なスプール２０と、スプール２０と対向するように配置され、緊急時に回転が阻止される回転体５０と、を備えている。ウェビング巻取装置１０は、基端部４２が保持され、回転体５０とスプール２０との間に配置され、緊急時に変形されてウェビング２０Ａが引き出された際に、スプール２０の内リブ２６に巻き付けられるワイヤ４０と、ワイヤ４０が内リブ２６に巻き付けられた際に、ワイヤ４０の先端部４８が逃げる逃げ部２４Ｂと、を備えている。【選択図】図３
