Abstract
A webbing retractor includes a spool around which a webbing is wound in such a manner as to be capable of being pulled out; an energy absorbing member which is deformed by the spool when a rotating force acting in a pulling-out direction of the webbing is applied to the spool at the time of a sudden deceleration of a vehicle, so as to prevent an increase in a tensile force of the webbing; a pretensioner which is connected to the spool when a deceleration of a predetermined value or more is applied, so as to rotate the spool in a taking-up direction of the webbing; and a canceling portion disposed between the spool and the pretensioner so as to cancel the stopping of rotation in a paying-out direction of the webbing by the pretensioner after operation of the pretensioner. Accordingly, after the operation of the pretensioner, the rotation of the spool in the pulling-out direction of the webbing is not restricted, and the energy absorption by the energy absorbing member is not restricted.
