Claims

[Scope of utility model registration request]

When the webbing is suddenly pulled out and the vehicle is rapidly moving, the engagement of the pole with the first rotating ring having ratchet teeth on its outer periphery causes the first rotating ring to rotate relative to the webbing take-up shaft. , this first
The lock mechanism can be actuated by the relative rotation of the rotating wheels to stop the rotation of the webbing take-up shaft in the webbing pull-out direction.Furthermore, a displacement body is disposed on the rotating body that rotates together with the webbing take-up shaft, and the webbing When the take-up shaft rotates in the webbing winding direction, the displacement body is restrained in the first posture and engages with the first rotating ring, thereby preventing relative rotation of the first rotating ring in the webbing winding direction with respect to the webbing take-up shaft. Webbing winding that prevents the webbing winding shaft from rotating in the webbing pull-out direction so that the displacement body can be displaced from the first posture by rotation of the webbing wind-up shaft in the webbing pull-out direction, thereby enabling relative rotation of the webbing wind-up shaft in the webbing pull-out direction with respect to the first rotating ring. is a collecting device,
A second rotating ring is provided coaxially with the first rotating ring and in parallel with the first rotating ring and is rotatable relative to the webbing take-up shaft, and ratchet teeth are formed on the outer periphery of the second rotating ring. However, when the displacement body is restrained in the first posture by rotation of the webbing take-up shaft in the webbing winding direction, the displacement body causes the ratchet of the second rotation ring to be attached to the valley of the ratchet teeth of the first rotation ring. A webbing take-up device, characterized in that the pole is not fitted into either the first rotating ring or the second rotating ring due to the position of the crest of the teeth.
