Abstract
A webbing take-up device 10 which takes up a webbing which is attached by a vehicle occupant, comprising: a rotor member 50 which rotates integrally with a take-up shaft 14 which takes up the webbing; a lock wheel 32 which is rotatably supported at the take-up shaft 14 and which rotates relatively with the take-up shaft 14, thereby deterring the take-up shaft 14. from rotating in a direction in which the webbing is pulled out; a slider 70 which engages the rotor member 50 and the lock wheel 32 with each other so as to deter the take-up shaft 14 and the lock wheel 32 from rotating relatively with each other between a state in which almost an entire amount of the webbing is taken up by the take-up shaft 14 and a state in which the entire amount of the webbing is taken up by the take-up shaft 14. As a result, it is possible to prevent end lock reliably.
