Claims

[Claims for Utility Model Registration] A take-up shaft for winding occupant restraint webbing in layers, and a winding shaft arranged to be rotatable relative to the winding shaft, and a rotation lag relative to the winding shaft due to rapid pulling out of the webbing. A webbing retractor is provided with a locking wheel in which a locking wheel occurs, and a retracting shaft rotation stop means for stopping rotation of the retracting shaft due to a rotation delay of the locking wheel, the webbing retractor being movably held in a fixed part of the device; A lock piece that moves to engage the lock ring and prevent rotation of the lock ring; and a lock piece that rotates following the rotation of the take-up shaft and moves the lock piece when a predetermined amount of webbing is wound up. A webbing retractor comprising: an operating gear that prevents rotation of a lock wheel; and a webbing retractor.
