Claims

[Scope of utility model registration request]

The sudden pull-out of the webbing and engagement with the pole causes the lock ring to rotate relative to the winding shaft,
The lock mechanism can be activated by the relative rotation of the lock ring to stop the rotation of the take-up shaft in the webbing pull-out direction.Furthermore, a displacement body is arranged on the rotating body that rotates together with the take-up shaft, and the When the displacement body rotates in the webbing winding direction, the displacement body is restrained in the first position and engages with the lock ring to prevent relative rotation of the lock ring in the webbing winding direction with respect to the winding shaft, and the webbing pulling direction of the winding shaft is prevented. The webbing retractor is a webbing retractor in which a displaceable body can be further displaced from a first posture by rotation, thereby enabling relative rotation of a take-up shaft with respect to a lock ring in a direction in which the webbing is pulled out, wherein the lock ring is engaged with the displaceable body. the second member is rotatable relative to the first member and engages with the pole, and the second member is moved in the webbing pulling direction with respect to the first member. The first
and a second member are connected so as to be integrally rotatable, and the relative rotatable angle between the first member and the second member is changed to a winding that rotates in the webbing drawing direction until the displacement body can be displaced from the first posture. A webbing take-up device characterized in that the rotation angle of a take-up shaft is greater than or equal to the rotation angle of a take-up shaft.
