Patent ID: 7681824

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 due to a rebound by stopping of taking up of the webbing belt to the spool, wherein the restriction unit is provided so as to be movable between a contact position, in which the restriction unit is in contact with the rotation detection member and is able to restrict displacement of the rotation detection member to the lock activation direction, and a non contact position, which is separated from the contact position and which allows displacement of the rotation detection member toward the lock activation direction; and the restriction unit includes a friction force generation member that generates a friction force due to rotation of the rotational body; and a displacement restriction member that is moved and biased into the contact position by the friction force generated by the friction force generation member.
