Abstract
In a webbing take-up device, in a state in which a stopper of a force limiter stopper mechanism has been brought into abutting contact with a stopper abutment portion resulting in rotation of a spool in a pull-out direction having become limited, the stopper is disposed on the inside of a flywheel hole portion of a flywheel body of a flywheel of a second force limiter mechanism. For this reason, deformation of the stopper outward in its radial direction can be suppressed by the flywheel body of the flywheel.
Claims8
A webbing take-up device comprising:
- a spool that is rotated in a pull-out direction due to webbing being pulled out therefrom;
- a lock rotor whose rotation is limited at a time of a vehicle emergency;
- a limiting member that is rotated and also moved in a direction of an axis of rotation due to the spool being rotated in the pull-out direction in a rotation-limited state of the lock rotor, and that limits rotation of the spool in the pull-out direction due to movement of the limiting member in the direction of the axis of rotation being limited;
- and
- a deformation suppressing member that is provided separately from the spool and the lock rotor, and that suppresses, from an outer side of the limiting member in a radial direction of the limiting member, deformation of the limiting member toward the outer side in the radial direction in a state in which movement of the limiting member in the direction of the axis of rotation is limited.
