To provide a seat belt retractor which can prevent an excessive load from acting on a seat belt.SOLUTION: A seat belt retractor includes: a spool which takes up a seat belt; a lock mechanism which allows rotation of the spool during non-operation time and prevents the rotation of the spool in a drawing direction of the seat belt during operation time; a first energy absorption mechanism which is deformed by the rotation of the spool in the drawing direction and prevention of the rotation by the lock mechanism; a power transmission mechanism which adds a second load generated by a motor and a speed reduction mechanism to a first load generated by deformation of the first energy absorption mechanism; and a second energy absorption mechanism which limits increase of a limit load generated by adding the second load to the first load by its deformation.SELECTED DRAWING: Figure 2

    【課題】過大な荷重がシートベルトに作用することを防止可能なシートベルトリトラクタの提供。【解決手段】シートベルトを巻き取るスプールと、非作動時に前記スプールの回転を許容し、作動時に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阻止するロック機構と、前記引き出し方向への前記スプールの回転と前記ロック機構による回転阻止とにより変形する第1のエネルギー吸収機構と、前記第1のエネルギー吸収機構の変形により発生する第1の荷重に、モータと減速機構により発生する第2の荷重を付加する動力伝達機構と、前記第1の荷重に前記第2の荷重を付加することにより生成される制限荷重の増大を自身の変形により制限する第2のエネルギー吸収機構とを備える、シートベルトリトラクタ。【選択図】図2
