PROBLEM TO BE SOLVED: To provide a seat belt retractor in which non-provisional locking of a drawing motion of a seat belt due to a small impact or the like can be suppressed irrespective of a tilt angle of the seat belt, and a stable motion of a lock mechanism can be assured.SOLUTION: On a top surface of a sensor lever 37, a groove part, which is configured by a rib, opens in left and right directions of a vehicle and extends in a vehicle longitudinal direction, is provided. Further, a ratchet lever 36 is provided with a protrusion which extends in the vehicle longitudinal direction from a tip of an arm part and is engaged with the groove part. Thus, during adjustment of a reclining angle and when the sensor lever 37 is displaced in linkage with movement of a ball 35 in the vehicle longitudinal direction, the protrusion 36j of the ratchet lever 36 is moved in a vehicle longitudinal direction along the top surface of the sensor lever 37 in the state such that the projection 36j is engaged with the groove part of the sensor lever 37. |
