Abstract
A webbing take-up device includes: a spool to which a base end portion of a long band-like webbing belt is attached and which is rotatable such that the webbing belt can be taken up and pulled out; and a rotating body that is coaxially relatively rotatable with respect to the spool. A coupling member, which causes the rotating body to rotate in a pullout direction together with the spool rotating in the pullout direction of the webbing belt when the coupling member is directly or indirectly engaged with the spool, is disposed on the rotating body. The webbing take-up device also includes: a lock member that regulates the rotation of the spool; acceleration detecting unit that is actuated when a vehicle disposed with the webbing take-up device abruptly decelerates; rotation detecting unit that is actuated by the abrupt rotation of the spool in the pullout direction and causes the coupling member to move to a position where the coupling member is engageable with the spool; and regulating unit that engages with the coupling member when the webbing belt has been taken up and accommodated onto the spool and regulates the displacement of the coupling member toward the engageable position.
