Patent ID: 7562840

Claim:
A webbing take-up device comprising: a spool to which a base end portion of a long band-like webbing belt is attached, with the spool taking up and accommodating the webbing belt as a result of the spool being rotated in a take-up direction that is one direction around its axis, and from which the webbing belt is pulled out as a result of the spool being rotated in a pullout direction opposite from the take-up direction due to the webbing belt being pulled toward its leading end; a rotating body that is coaxially relatively rotatable with respect to the spool; a coupling pawl that is movably mounted on the rotating body such that it is displaceable between a position where the coupling pawl is directly or indirectly engaged with the spool and a position where the coupling pawl disengages from the spool, and when the coupling pawl is directly or indirectly engaged with the spool, the coupling pawl causes the rotating body to rotate in the pullout direction together with the spool rotating in the pullout direction; a lock member that directly or indirectly engages with the spool in conjunction with the rotating body rotating in the pullout direction and regulates the rotation of the spool in the pullout direction; an acceleration detecting unit that is actuated when a vehicle disposed with the webbing take-up device abruptly decelerates, and which causes the coupling pawl to move on the rotating body to the engaged position; a rotation detecting unit including a W pawl that is actuated by an abrupt rotation of the spool in the pullout direction such that movement of the W pawl causes the coupling pawl to move on the rotating body to the engaged position; and a regulating unit that engages with the coupling pawl when the webbing belt has been taken up and accommodated onto the spool and regulates the displacement of the coupling pawl toward the engaged position, including a rotating member that rotates substantially coaxially with respect to the spool, and one regulating portion integrally disposed on the rotating member that limits displacement of the coupling pawl toward the engaged position.
