項に記載のウエビング延出し防止装置。[Claims for Utility Model Registration] (1) Used in a webbing retractor equipped with a locking means that prevents the rotation of a take-up shaft in the direction of pulling out the webbing in the event of a vehicle emergency. a roller disposed at a predetermined interval from the outer periphery of the layered webbing wound around the take-up shaft, the middle part of the webbing is wound around the roller, and the roller is brought into contact with the outer periphery when the locking means is actuated; A moving means is provided between the winding shaft and the moving means to move the roller toward or away from the winding shaft, and the amount of movement of the roller by the moving means is adjusted to adjust the winding diameter of the layered webbing according to the webbing being pulled out or wound up. A webbing extension prevention device comprising: a deceleration mechanism section that maintains the predetermined interval by the same amount as the amount of change in the radial dimension. (2) A sub-roller is disposed on the outer periphery of the layered webbing and is rotated as the webbing is pulled out or wound up by a biasing force, and the roller is disposed at a predetermined interval from the sub-roller. Claim No. (1) of the said utility model registration claim
The webbing extension prevention device described in .
