Locking member mounting structure of seat belt retractor

摘要

Provided is a locking member mounting structure of a seat belt retractor including: a locking base (710) coupled to one side of a guide drum; a locking clutch (750) rotatably coupled to one side surface of the locking base (710); a lock arm (760) coupled to one side surface of the locking clutch (750) so as to rotate at a predetermined angle; and a mechanism cover covering the locking clutch (750) and the lock arm (760), wherein a leaf spring (755) is fixed to extend to one side from a boss (751) formed in the center of the locking clutch (750), and a fixing piece projects from one surface of the lock arm (760) so as to be fixed to the leaf spring (755). The leaf spring which returns the lock arm installed in the locking clutch is easily assembled, and assembly time of the leaf spring is reduced, thereby increasing productivity. Further, since the leaf spring has a curved portion or is formed in a stair shape, elasticity of the leaf spring is maintained, and deformation of the leaf spring is prevented.
