Abstract
A webbing retractor comprises a spool around which a webbing capable of being unwound therefrom is wound; a pretensioner for rotating said spool in a webbing winding direction when a deceleration of a predetermined value or more is applied during a sudden deceleration of a vehicle; an energy absorbing member put in a coupled state with said spool, rotated integrally with said spool and deformed by said spool to prevent an increase in tension of the webbing when rotational force in a webbing unwinding direction acts upon said spool after said spool has been rotated in said webbing winding direction by said pretensioner; and a cancelling portion applied with the rotational force in said webbing unwinding direction via said energy absorbing member when the energy absorbing member is deformed by the rotational force in said webbing unwinding direction, for cancelling the state in which rotation of said spool in the webbing unwinding direction is stopped by said pretensioner. Therefore, after the spool is rotated in the webbing winding direction by the pretensioner, the spool is rotatable in the webbing unwinding direction.
