PROBLEM TO BE SOLVED: To provide a webbing retractor capable of appropriately adjusting the magnitude of a resistance applied to a spool.SOLUTION: A webbing retractor 10 includes: a first FL mechanism 36 interlocked with the rotational acceleration of a spool 18 in the pull-out direction at a vehicle emergency time; and a second FL mechanism 56 interlocked with the rotation speed of the spool 18 in the pull-out direction at the vehicle emergency time. Therefore, even if the rotation speed of the spool 18 in the pull-out direction is slow at the start of operation of the first FL mechanism 36 and the second FL mechanism 56, since the inertia force applied to a first FL flywheel 52 of the first FL mechanism 36 is large, resistance applied to the spool 18 against rotation in the pull-out direction can be appropriately set.SELECTED DRAWING: Figure 1

    【課題】スプールに付与される抵抗の大きさを適切にできる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10は、車両緊急時におけるスプール18の引出方向への回転加速度に連動する第1FL機構36と、車両緊急時におけるスプール18の引出方向への回転速度に連動する第2FL機構56と、を備えている。このため、第1FL機構36及び第2FL機構56の作動開始時にスプール18の引出方向への回転速度が遅くても、第1FL機構36の第1FLフライホイール52に作用される慣性力が大きいため、スプール18に付与される引出方向への回転に対する抵抗を適切にできる。【選択図】図1
