Claims

[Scope of utility model registration request]

A take-up shaft that winds up webbing for passenger restraints, a lock ring that follows the rotation of this take-up shaft in the direction of pulling out the webbing, and a lock ring that is actuated by an acceleration sensor to prevent rotation of the lock ring and lock the lock ring against the take-up shaft. a ball lever that causes a rotation delay with respect to the take-up shaft; a lock means that stops the rotation of the webbing pull-out of the take-up shaft when the lock ring has a rotation delay with respect to the take-up shaft; A rotary plate that corresponds to the pole lever through a connecting means and limits the operation of the pole lever by rotational force during webbing winding, and a rotary plate provided between the rotary plate and the winding shaft to reduce the rotational force of the winding shaft by frictional force. a transmission means for transmitting the transmission to the rotary plate via the transmission means; and a friction force adjustment means that is capable of adjusting the friction force to the transmission means to be strong or weak and reverses in response to the resistance force from the pawl lever to weaken the friction force. A locking mechanism for a webbing retractor having the following.
