Abstract
A webbing take-up device includes a spool taking up webbing worn by an occupant, that is rotated in a pull-out direction by the webbing being pulled-out; a base lock that is provided capable of rotating integrally with the spool and restricts rotation of the spool in the pull-out direction in vehicle-emergency; a pawl that is rotated together with the spool and, by being displaced, engages with a winding ring and transmits rotation force of the spool to the winding ring, and a trigger ring including a restricting portion that is disposed in a restricting position at which displacement of the pawl is restricted in a state prior to the spool being rotated with respect to the base lock, and is disposed in a permitting position at which displacement of the pawl is permitted when the spool has been rotated in the pull-out direction with respect to the base lock.
