PURPOSE:To prevent an automatic lock function from being inadvertently released by returning the rotating end part of a transmission means to the first guide part of a control panel by the rotation of a winding shaft on which webbing is wound by specified turns to prevent an inertia sensing means from being started by the transmission means. CONSTITUTION:A control plate 22 is started to rotate while being decelerated by an idle gear 21, and the engaging projection 23a of a lever 23 follows an outer cam groove 22a. When the engaging projection 23a comes at the notched part 22d of the control plate 22, it does not enter into the inner cam groove 22b because the engaging projection 23a is energized in the direction that it is pressed against the outer wall of the outer cam groove 22a. In this way, In this way, while the engaging projection 23a comes within the outer cam groove 22a of the control plate 22, the engaged part 24a of a lock arm 24 is engaged with the teeth of a latch plate 4a and an inertia sensitive means is not operated. In this case, it is in a normal emergency lock mechanism operating condition, and an automatic lock mechanism is in a non-operating condition. |
