Abstract
There is provided a seat belt apparatus which not only can reduce the possibility that an end lock phenomenon can occur when removing the mounting of a webbing but also, even in case where the end lock phenomenon occurs, can remove the end lock phenomenon easily. That is, in a seat belt apparatus including a seat belt retractor having a lock mechanism structured such that, when the acceleration of a vehicle body or the pay-out acceleration of a webbing is a predetermined value or more, a pawl member ( ) is engaged with a pawl wheel ( ) to lock the rotation of a bobbin ( ) with the webbing wound thereon in the webbing pay-out direction, the pawl wheel ( ) is structured such that two or more kinds of ratchet teeth (T ) and (T ) differing in addendum circle diameter are mixedly arranged in the peripheral direction of the pawl wheel according to a predetermined manner, thereby being able to lower the probability of the webbing end lock occurring.
