Abstract
A webbing winding device includes: a spool around which webbing to be worn by an occupant is wound and which is rotated in a pull-out direction by the webbing being pulled out; a trigger member provided at the spool; a torsion shaft engaged with the spool and twisted to allow rotation of the spool in the pull-out direction; and a clutch with which the torsion shaft is engaged and the trigger member is engaged, and in which part of a member engaged with the torsion shaft so as to be relatively non-rotatable is locked to the trigger member to restrict rotation of the torsion shaft with respect to the spool, the clutch being operated by being released by actuation of the trigger member and engaged with a lock member to restrict rotation with respect to the lock member.
