<p><P>PROBLEM TO BE SOLVED: To provide a compact structure for preventing end lock while effectively preventing end lock by a belt delivery sensor. <P>SOLUTION: When an eccentric gear 14 is rotated as a seat belt is retracted/delivered, a pair of stoppers 45, 46 are moved in the diameter direction of a spool along guide grooves 47, 48 of the eccentric gear 14 of an ELR-ALR changing mechanism 25 while being controlled by a cam groove 49 formed in a case 10. When the substantially full amount of the seat belt is retracted, the stoppers 45, 46 are located at large diameter side arc-shaped grooves 49c, 49d, and press an inner circumferential surface of a ring part 12b to prevent rocking of a flywheel 12. When the seat belt is delivered by the predetermined amount from the fully retracted condition, the stoppers 45, 46 are located at small diameter side arc-shaped grooves 49a, 49b not to press the inner circumferential surface of the ring part 12b, allowing the flywheel 12 to be freely rocked. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
