Abstract:
1. A webbing take-up device comprising: a spool that rotates in a take-up direction so as to take up a webbing thereon and rotates in a pull-out direction by the webbing being pulled out therefrom; a lock mechanism that stops rotation of the spool in the pull-out direction by the lock mechanism being operated; an ALR pawl that is movable between a lock position where the ALR pawl and the lock mechanism are engaged so that the lock mechanism is operated, and a release position where engagement of the ALR pawl and the lock mechanism is released; a switching cam that is connected to the spool via a speed reduction mechanism which reduces rotation of the spool, and rotates interlockingly with rotation of the spool; a control disk that is provided so as to be coaxial with the switching cam and that includes a holding portion, the holding portion being pressed by the switching cam so as to rotate interlockingly with the switching cam, and the holding portion abutting with the ALR pawl so as to hold the ALR pawl at the release position between from a maximal taken-up state where the webbing is maximally taken up on the spool to a state which is near a maximal pulled out state where the webbing is maximally pulled out from the spool; a pressing portion that is integrally formed with the switching cam, an extension portion that extends from the pressing portion in the take-up direction of the switching cam and that is configured to be able to abut with the ALR pawl to maintain the ALR pawl in the release position in the event that the ALR pawl climbs over the pressing portion as a result of rotational over-travel of the switching cam in the pull-out direction of the switching cam.
