Abstract
A webbing retractor is provided that can improve balance of load that a torsion shaft receives from a spool. Fit-together projections are formed at a spool side engaging portion of a main torsion member. Further, a load receiving portion is formed at a webbing insert-through hole side at the spool side engaging portion. Rotation radius direction components of rotational forces, that respective inclined surfaces of the fit-together projections receive from respective inclined surfaces of rotation restricting holes, are nullified by a rotation radius direction component of rotational force that the load receiving portion receives from a load imparting portion. Due thereto, balance of load that the main torsion member receives from a spool can be improved.
