A webbing take-up device comprising: a spool including a webbing insertion hole at which a webbing to be applied to a vehicle occupant is inserted, the webbing being taken up onto the spool, and the spool being turned in a pull-out direction when the webbing is pulled out; a stopper member provided at an end portion of the webbing, the stopper member securing the end portion of the webbing at the spool by engaging with a periphery portion of the webbing insertion hole; and a load bracing portion (P2, P5) disposed at a diametric direction inner side of the spool relative to the stopper member, the load bracing portion (P2, P5) bracing a load that is applied to the spool from the webbing via the stopper member, wherein: the stopper member is formed in a long shape whose length direction is along an axial direction of the spool; and the load bracing portion (P2, P5) is provided at each end portion (15B, 15A) at a length direction one side and another side of the stopper member, where locations at the load bracing portion (P2, P5) oppose the spool in the diametric direction, and wherein: a lock portion is provided at an axial direction one side of the spool, turning of the lock portion in the pull-out direction being limited during an emergency state of a vehicle; a torsion shaft is provided at an axial central portion of the spool, a portion of the torsion shaft serving as a first coupling portion that is coupled to an end portion at an axial direction other side of the spool, another portion of the torsion shaft serving as a second coupling portion that is coupled to the lock portion, and, when the turning of the lock portion is limited, the torsion shaft allowing turning of the spool in the pull-out direction relative to the lock portion by a load of at least a force limiter load; and a portion of at least one of the first coupling portion and the second coupling portion serves as the load bracing portion (P2, P5). a spool including a webbing insertion hole at which a webbing to be applied to a vehicle occupant is inserted, the webbing being taken up onto the spool, and the spool being turned in a pull-out direction when the webbing is pulled out;
