Claims

[Scope of utility model registration request]

A take-up shaft that is rotatably supported by the frame and winds up the webbing worn by the occupant; a lock gear that rotates in the webbing take-up direction when the vehicle suddenly decelerates; and a lock gear that is linked to the take-up shaft to suddenly decelerate the vehicle. The lock wheel sometimes has a rotation delay with respect to the webbing pulling direction of the take-up shaft, and the lock wheel moves due to the rotation delay with respect to the take-up shaft and engages with the lock gear, thereby preventing the rotation of the take-up shaft in the webbing pulling direction. and lock gear rotation limiting means disposed between the lock gear and the frame to allow rotation of the lock gear in the webbing winding direction but to prevent rotation of the lock gear in the webbing pulling direction. Characteristic webbing retractor.
