Abstract
In a webbing take-up device, due to actuation of a pre-tensioning mechanism when a vehicle collision, a piston is moved, rack teeth of the piston mesh with pinion teeth of a pinion, causing the pinion rotate and a spool to be rotated in the take-up direction. In a state where a large rotational force in the pull-out direction is acting from an occupant on the pinion, through a webbing and the spool, a rack tooth is broken by a pinion tooth when the rack teeth initially mesh with the pinion teeth, especially by a tip end of the rack tooth meshing with the pinion tooth. Therefore, sticking-in of the pinion teeth rack teeth and the pinion teeth can be suppressed, or easily eliminated, enabling loss in force transmitted from the piston to the pinion to be reduced.
