Abstract

A webbing take-up device includes: a spool that takes up webbing worn by an occupant and is rotated in a pull-out direction due to the webbing being pulled out; a base lock that is provided capable of rotating integrally with the spool and is restricted from rotating in the pull-out direction of the spool in vehicle emergency; a pawl that is rotated together with the spool and that, by being displaced to an engaged position, engages with a winding ring and transmits rotation force of the spool to the winding ring; and a trigger ring that is provided capable of being displaced in a rotation circumferential direction of the spool with respect to the spool and includes a pawl-abut portion, abutting the pawl and displacing the pawl to the engaged position when the spool is rotated in the pull-out direction with respect to the lock section.
