摘要

A vehicle seat belt retractor (10) includes a frame (12) supporting a spool (50) on which seat belt webbing (72) is wound for rotation in belt withdrawal (76) and belt retraction (75) directions. A lever (196) for use in preventing rotation of the spool (50) in the belt withdrawal direction (76) has a cylindrical portion (220) and a key (224) extending radially outward from the cylindrical portion (220). The lever (196) is supported for pivotal movement on a support member (112) that has a cylindrical chamber (222) for receiving the cylindrical portion (220) of the lever (196). A keyway (226) extends radially outward from the cylindrical chamber (222) for receiving the key (224) of the lever (196). The keyway (226) includes a surface (227) engageable by the key (224) of the lever (196) to prevent axial movement of the cylindrical portion (220) out of the cylindrical chamber (222).
