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 for preventing the webbing unwinding rotation of the take-up shaft that causes a rotational delay between the lock ring and the take-up shaft; an acceleration sensor that applies a resistance force to the following rotation of the lock ring; and a protrusion that receives the rotational force of the winding shaft in which two states, ie, a biasing state toward the lock ring and a biasing state in the separating direction, can be selected. When the webbing take-up amount exceeds a predetermined value, the webbing is biased away from the lock ring, and when the webbing unwinding amount reaches a predetermined value, it is biased toward the lock ring, causing the lock ring to rotate. A webbing retractor comprising: a control means for applying resistance; and a release means for biasing the control means in the direction of separating the lock ring by an operation of an occupant.
