Claims

[Scope of utility model registration request]

A lock ring that rotates following a take-up shaft of webbing for occupant restraint; a locking means that prevents the take-up shaft from unwinding the webbing when the lock ring lags in rotation with respect to the take-up shaft; An acceleration sensor that applies a resistance force to the follow-up rotation of the lock ring in an emergency, and two states of biasing in the approach direction and biasing in the FF direction to the lock ring are selectable, and the amount of webbing taken up is equal to or higher than a predetermined value. a control means for resisting the rotation of the lock wheel by biasing the webbing toward the lock wheel when the unwinding amount of the webbing is biased away from the lock ring at a predetermined value or more; A webbing take-up device comprising: a holding means that receives the rotational force of a take-up shaft and separates the control means from a lock ring by a certain amount during take-up.
