PROBLEM TO BE SOLVED: To provide a webbing take-up device in which a force limiter member can deform according to a rotating speed, based upon a drawing-out speed of webbing, of a spool in a drawing-out direction.SOLUTION: In the present webbing take-up device, a base part 51 and an engagement part 52 of a wire 46 are rotated with centrifugal force when a rotating speed of a spool 18 in a drawing-out direction becomes equal to or larger than a predetermined speed. In this state, when the spool 18 is rotated in the drawing-out direction to a lock gear 32, the engagement part 52 of the wire 46 enters inside of a wire holding part 60 from a take-up directional side, so that the engagement part 52 of the wire 46 is stopped by the wire holding part 60 from rotating in the drawing-out direction. Consequently, a wire body 48 of the wire 46 is drawn out of a wire insertion hole 44 of the spool 18.SELECTED DRAWING: Figure 2 【課題】ウェビングの引出速度に基づくスプールの引出方向への回転速度に応じてフォースリミッタ部材の変形が可能なウェビング巻取装置を得る。【解決手段】本ウェビング巻取装置では、スプール１８の引出方向への回転速度が所定の大きさ以上になると、ワイヤ４６の基部５１及び係合部５２が遠心力によって回動される。この状態で、スプール１８が、ロックギヤ３２に対して引出方向へ回転されると、ワイヤ４６の係合部５２が、巻取方向側からワイヤ保持部６０の内側へ入り、ワイヤ４６の係合部５２はワイヤ保持部６０によって引出方向への回転が阻止される。このため、スプール１８のワイヤ挿入孔４４からワイヤ４６のワイヤ本体４８が引出される。【選択図】図２
