To provide a seat belt retractor which can increase resistance exerted on webbing when energy is absorbed while inhibiting increase of friction resistance during steady drive of a pretensioner, and to provide a seat belt device.SOLUTION: A seat belt retractor 1 includes a guide member 7 which faces at least a part of an outer peripheral surface of a locking base 6 and is arranged along an opening 32a. The guide member 7 is configured so as to avoid contacting with the locking base 6 until a pretensioner 4 shifts to a steady drive state, to contact with the locking base 6 during steady drive of the pretensioner 4, and to allow contact between lock teeth 32b and the locking base 6 when a predetermined load is applied after the pretensioner 4 shifts to the steady drive state.SELECTED DRAWING: Figure 3

    【課題】プリテンショナの定常駆動時における摩擦抵抗の増大を抑制しつつ、エネルギー吸収時におけるウェビングに負荷される抵抗の増大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、ロッキングベース6の外周面の少なくとも一部に対峙するとともに開口部32aに沿って配置されたガイド部材7を備え、ガイド部材7は、プリテンショナ4が定常駆動状態に移行するまでロッキングベース6と接触しないように構成されており、プリテンショナ4の定常駆動時にロッキングベース6と接触するように構成されており、プリテンショナ4が定常駆動状態に移行した後で所定の荷重が負荷されたときにロック歯32bとロッキングベース6との接触を許容するように構成されている。【選択図】図3
