Webbing take-up device

A webbing take-up device comprising:

• a spool that rotates in a pull-out direction by a webbing being pulled out;
• a first energy absorption member that extends along an axial center of the spool, that has one end portion engaged with the spool such that the first energy absorption member is capable of rotating integrally with the spool, and that is configured so as to be capable of undergoing torsional deformation;
• a lock mechanism that is engaged with another end portion of the first energy absorption member so as to be capable of rotating integrally with the first energy absorption member, and that actuates to block rotation of the first energy absorption member in the pull-out direction at least one of when a vehicle suddenly decelerates or when the spool suddenly rotates in the pull-out direction;
• an energy absorption mechanism that includes a second energy absorption member, that actuates by being coupled to the spool, and that deforms the second energy absorption member;
• and
• a pawl that is provided at the spool, that actuates by the spool rotating in the pull-out direction relative to the lock mechanism, and that couples the spool and the energy absorption mechanism.
