Abstract
It is an object to prevent end locking in which a webbing can neither be drawn out nor wound due to erroneous operation of an emergency lock mechanism at the time of retracting a belt. When almost all the webbing 50 is wound, not only a retaining wall 41c of a rotation control disc 41 regulates an engaging catch 26b of a lock arm 26 so that the engaging catch 26b does not move in the direction of engaging with an internal gear 34a of a gear case 34, but also a projection 12 arranged so as to project from a bobbin 3 engages with the lock arm 26 that is unengaged with the internal gear 34a, which in turn blocks a rachet wheel 18 from rotating with a delay with respect to the bobbin 3. As a result, a pole 16 that is operated by the rachet wheel 18 rotating with a delay with respect to the bobbin 3 is held in an inoperative condition in which the pole 16 is not engaged with engaging internal teeth 2.
