Patent ID: 8727258

Claim:
A webbing winding device comprising: a spool that fixes a base end portion of an elongated webbing belt in a longitudinal direction, and rotates in a winding direction so as to allow the webbing belt to wind around the spool from the base end portion of the webbing belt in the longitudinal direction; a regulation member that rotates, so as to directly or indirectly engage with the spool, by a predetermined angle toward a position at which the regulation member directly or indirectly engages with the spool, and that regulates the rotation of the spool in an extracting direction opposite to the winding direction; a rotation member that is operated to connect the spool and the rotation member in a connection state of at least one of two cases, one case being a case in which the spool rotates in the extracting direction at a predetermined spool acceleration or more in accordance with extraction of the webbing belt from the spool and the other case being a case in which a vehicle is decelerated at a predetermined vehicle acceleration or more, and that rotates in a predetermined direction in accordance with rotation transmitted from the spool in the connection state; and a link member that directly contacts the regulation member and mechanically connects the rotation member and the regulation member to each other, and transmits rotation of the rotation member in the extracting direction to the regulation member so as to rotate the regulation member in a direction of enabling direct or indirect engagement with the spool.
