Claims

[Scope of utility model registration request]

Webbing to be worn on an occupant, a take-up shaft for winding up the webbing, a locking wheel that can rotate relative to the take-up shaft when the webbing is suddenly pulled out and a pole driven by an acceleration sensor is locked; A webbing retractor comprising a locking means for locking the rotation of the take-up shaft by relative rotation between the lock ring and the take-up shaft, and the webbing retractor locks the lock ring and the take-up shaft when the amount of webbing to be taken up is more than a predetermined amount. A restriction that limits the movement of the pole while allowing non-relative rotation between the lock ring and the winding shaft, and when the amount of webbing taken up is less than a predetermined amount, releases the restriction on the movement of the pole while allowing relative rotation between the lock ring and the winding shaft. A webbing take-up device comprising: means.
