Patent ID: 7942361

Claim:
A webbing retracting device comprising: a spool that, by rotation in a take up direction, takes up a longitudinal band-shaped webbing belt from a base end side of webbing belt and stores the webbing belt thereon; a rotational body provided so as to be able to rotate relative to the spool and connected to the spool so as to be able to rotate to follow rotation of the spool; a lock member that restricts rotation of the spool in a pull out direction by activation thereof; a rotation detection member, provided at the rotational body, that is displaced toward a predetermined lock activation direction to activate the lock member when the rotational body rotates in the pull out direction at a predetermined velocity or greater; and a restriction unit, provided at the rotational body, that restricts displacement of the rotation detection member toward the lock activation direction such that said lock member is not activated due to a rebound caused by stopping of taking up of the webbing belt to the spool, wherein the restriction unit is activated by centrifugal force generated by the rotating of rotational body.
