Abstract
The rotatable locking section engages with the fixed locking section resulting in pull-out direction rotation of the spool being locked. The webbing take-up device includes a permanent magnet and an electromagnet that restrict displacement of the rotatable locking section toward the fixed locking section, and that are actuated in a vehicle emergency so as to displace the rotatable locking section toward the fixed locking section. A restricting force of the rotatable locking section by the permanent magnet and the electromagnet is set such that the rotatable locking section is displaced toward the fixed locking section by an inertial force that spins the rotatable locking section about its own center of rotation when the electromagnet is deactivated and the spool has been rotated in the pull-out direction with an angular acceleration greater than a predetermined angular acceleration.
