PROBLEM TO BE SOLVED: To effectively increase an allowable load of an allowance mechanism.SOLUTION: In a second force limiter mechanism 30 in a webbing rewinding device 10, a planetary gear 34 of a planetary gear mechanism 32 transmits rotation of a spool 16 in a drawing-out direction to a rotating gear 38A of a second torsion shaft 38 in a state where a centrifugal clutch 42 is operated to restrict rotation of an outer gear 36 of the planetary gear mechanism 32, thereby the rotating gear 38A is rotated at rotation speed larger than rotation speed of the spool 16, so that the second torsion shaft 38 is torsionally-deformed. Thus, a force limiter load of the second force limiter mechanism 30 can be effectively increased.SELECTED DRAWING: Figure 1

    【課題】許容機構の許容荷重を効果的に大きくする。【解決手段】ウェビング巻取装置10では、第2フォースリミッタ機構30において、遠心クラッチ42が作動されて、遊星歯車機構32のアウタギヤ36の回転が規制された状態で、遊星歯車機構32の遊星ギヤ34がスプール16の引出方向への回転を第2トーションシャフト38の回転ギヤ38Aに伝達することで、スプール16の回転速度よりも大きい回転速度で回転ギヤ38Aが回転されて、第2トーションシャフト38が捩れ変形される。このため、第2フォースリミッタ機構30のフォースリミッタ荷重を効果的に大きくできる。【選択図】図1
