To provide a seat belt retractor and a seat belt device that are capable of improving performance of energy absorption characteristics while reducing a webbing operation burden during normal time.SOLUTION: A seat belt retractor 1 is provided with: a spool 2 that takes up a webbing for binding an occupant; a shaft 3 that is disposed in the shaft center of the spool 2 and capable of relatively rotating the spool 2 when a prescribed load is applied on the webbing; a lock mechanism 4 capable of arresting rotation of the shaft 3; an energy absorption device 5 that attenuates the kinetic energy of the relative rotation generated in the spool 2 during the rotation arrest of the shaft 3; and a clutch mechanism 6 for maintaining the energy absorption device 5 in an off-state where an operation is inhibited during normal time when the relative rotation does not occur, and switching the energy absorption device 5 to an on-state where the operation is permitted in emergency where the relative rotation occurs.SELECTED DRAWING: Figure 1

    【課題】通常時におけるウェビングの操作時の負担を軽減しつつエネルギー吸収特性の性能向上を図ることができる、シートベルトリトラクタ及び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1は、乗員を拘束するウェビングの巻き取りを行うスプール2と、スプール2の軸心に配置されるとともにウェビングに所定の荷重が負荷されたときにスプール2を相対回転させ得るシャフト3と、シャフト3の回転を拘束可能なロック機構4と、シャフト3の回転拘束時にスプール2に生じる相対回転の運動エネルギーを減衰させるエネルギー吸収装置5と、を備え、前記相対回転が生じない通常時にエネルギー吸収装置5を作動不可能なオフ状態に保持し、前記相対回転が生じ得る緊急時にエネルギー吸収装置5を作動可能なオン状態に切り換えるクラッチ機構6を備えている。【選択図】図1
