Claims

[Claims for Utility Model Registration] A take-up shaft that winds up occupant restraint webbing in layers; and a webbing drawer of the take-up shaft that is disposed so as to be able to engage with the take-up shaft and moves into a meshing state. A locking means for preventing directional rotation, which normally rotates following the winding shaft and holds the locking means in a non-engaged state with the winding shaft, and when the rotation is stopped, the locking means is brought into the meshing state. A lock wheel that guides the lock wheel, a pawl lever that is disposed so as to be able to engage with the lock wheel and prevents rotation of the lock wheel when in the engaged state, and a pawl lever that is actuated by detecting a sudden vehicle deceleration state by inertia force and engages the pawl lever with the lock wheel. In the webbing retractor, the pawl lever includes an elastically deformable engagement portion that engages with the lock ring to prevent rotation, and an elastic deformation of the engagement portion. 1. A webbing take-up device, characterized in that a limiting portion is formed to limit the webbing to a predetermined range.
