To suppress a take-up load of a seat belt.SOLUTION: A seat belt device comprises a seat belt, a tongue attached to the seat belt, a buckle for insertion and withdrawal of the tongue, and a seat belt retractor. The seat belt retractor has a spool for taking up the seat belt, a generator for generating electric power in conjunction with the rotation of the spool, a detection unit for detecting a belt non-fastened state in which the tongue is withdrawn from the buckle, a locking mechanism for performing a locking operation of locking the rotation of the spool in a pull-out direction of the seat belt, and a cancellation mechanism for cancelling the locking operation by using the electric power generated by the generator when the belt non-fastened state is detected by the detection unit.SELECTED DRAWING: Figure 7

    【課題】シートベルトの巻き取り負荷を抑制すること。【解決手段】シートベルトと、前記シートベルトに取り付けられたタングと、前記タングが挿抜されるバックルと、シートベルトリトラクタとを備え、前記シートベルトリトラクタは、前記シートベルトを巻き取るスプールと、前記スプールの回転に連動して発電するジェネレータと、前記タングが前記バックルから抜き取られたベルト非装着状態を検知する検知部と、前記シートベルトの引き出し方向への前記スプールの回転をロックするロック動作を行うロック機構と、前記ベルト非装着状態が前記検知部により検知されている場合、前記ジェネレータで発電した電力を使用して前記ロック動作をキャンセルするキャンセル機構とを有する、シートベルト装置。【選択図】図7
