Abstract
A notched ring rotates together with a spool and opposes a disk of a locking shaft portion. A substantially semicircular engaging projection is formed on an opposing surface of the notched ring in the peripheral direction thereof. An engaging concave portion is formed at the disk so as to correspond to the engaging projection. When the spool is rotated in the withdrawing direction of a webbing and the opposing surface of the notched ring abuts the disk, the engaging projection enters and engages the engaging concave portion without clearance therebetween. Accordingly, even if rotating force is further applied to the spool in the withdrawing direction of the webbing, movement of the notched ring in the outer peripheral direction is prevented, and a state in which the rotation of the spool is restricted is maintained.
