To prevent a load such as a clamping force or a rubbing force from acting on a cord-like material when the cord-like material is pulled in a direction that turns on a brake device. When a shutter curtain (1), which is an opening/closing body performing opening/closing movements, comes into contact with an obstacle during a closing movement, a locking wire (36), which is a cord-like member, is joined with the curtain, and a tensioning force that acts on the wire causes the brake device to be turned on and the closing movement of the curtain is stopped. A pulling device (56) that pulls the wire in a direction that turns on the brake device at the same time when and/or after the curtain comes into contact with the obstacle is provided on the curtain. The pulling device is configured as a device which causes a winding device (40), which is a device for feeding out the wire during a closing movement of the curtain, to perform an operation to wind the wire, a device which makes a linear portion of the wire non-linear by using a rotatable pressure member, a device which causes a rotatable guide member that guides the wire to perform a movement, and a device which causes the winding device to perform a movement. |
