In a webbing retractor, in a state where a second anchored portion of a sub torsion shaft is connected to a frame via a rotation impeding mechanism, when a spool is pulled by excessive tension that is applied to a webbing, there is a tendency for the spool to tilt with respect to a sleeve that is supported at the frame via the rotation impeding mechanism. In this case, a distance between a second energy absorbing portion of the sub torsion shaft and an inner peripheral surface of an insert-through hole changes. A change in the distance becomes large at an opening side of the insert-through hole, but an inner diameter of the insert-through hole is enlarged at the opening side. Due thereto, it can be made such that the second energy absorbing portion does not interfere with the inner peripheral surface of the insert-through hole.
