Provided are a seatbelt retractor and a seatbelt device that can suppress an increase in frictional resistance during stable driving of a pretensioner and can increase resistance applied to a webbing during energy absorption. The webbing retractor (1) is provided with a guide member (7) that faces at least a part of the outer peripheral surface of the lock base (6) and is disposed along the opening (32a), and the guide member (7) is configured so as not to come into contact with the lock base (6) until the pretensioner (4) transitions to a stable driving state, and so as to come into contact with the lock base (6) when the pretensioner (4) is stably driven. The locking teeth (32b) are configured so as to permit contact between the locking teeth (32b) and the locking base (6) when a predetermined load is applied after the pretensioner (4) transitions to the stable driving state.

    提供能够抑制预紧器的稳定驱动时的摩擦阻力的增大并实现能量吸收时的向织带施加的阻力的增大的安全带卷收器及安全带装置。安全带卷收器(1)具备与锁定底座(6)的外周面的至少一部分对置并且沿着开口部(32a)配置的引导构件(7),引导构件(7)构成为直到预紧器(4)转变为稳定驱动状态为止不与锁定底座(6)接触,构成为在预紧器(4)的稳定驱动时与锁定底座(6)接触,且构成为在预紧器(4)转变为稳定驱动状态后被施加了预定的载荷时容许锁定齿(32b)与锁定底座(6)的接触。
