PROBLEM TO BE SOLVED: To provide a seat belt retractor which has simple structure, can be easily manufactured, and can be exactly actuated, and a seat belt device with the same.SOLUTION: A seat belt retractor is provided with energy absorption mechanisms 15, 16 for absorbing and alleviating energy of crew members by restricting loads to act on a seat belt, in which the energy absorption mechanisms 15, 16 have: a first energy absorption mechanism 15 which is concentrically built in a spool 9, one end of which is held by the spool 9, the other end of which can be locked by a lock mechanism 10, and to which rotational force is imparted by a torsion; and a second energy absorption mechanism 16 including: a first rotary member 9a which is rotatable with the spool 9; a contact member 18 which is provided to be relatively rotatable only at a predetermined angle to the first rotary member 9a; a second rotary member 19 which is provided to be relatively rotatable to the contact member 18; and an energy absorption member 17 one end of which is fixed and supported to the second rotary member 19, and the other end of which is brought into contact with the contact member 18.SELECTED DRAWING: Figure 2

    【課題】簡単な構造で、容易に作製可能であって、的確に作動することが可能なシートベルトリトラクタおよびこれを備えているシートベルト装置を提供する【解決手段】シートベルトリトラクタは、シートベルトに作用する荷重を制限して乗員のエネルギを吸収緩和するエネルギ吸収機構15,16と、を備え、エネルギ吸収機構15,16は、スプール9内に同心に内蔵され、一端部がスプール9に保持され、他端部がロック機構10でロック可能であって、ねじり力で回転力が付与される第1のエネルギ吸収機構15と、スプール9と共に回転可能な第1回転部材9a、第1回転部材9aに対して所定角度のみ相対回転可能に設けられる当接部材18、当接部材18に対して相対回転可能に設けられる第2回転部材19、及び、一端部が第2回転部材19に固定支持され、他端部が当接部材18に当接されるエネルギ吸収部材17、を含む第2のエネルギ吸収機構16と、を有する。【選択図】図2
