摘要：PROBLEM TO BE SOLVED: To provide an interlocking opening/closing device for both sliding doors different in door widths, and a fire door. SOLUTION: Pulleys 5, 5 are provided in upper positions when the sliding doors are fully opened, and a wire rope 7 passed through a cylindrical guide implement 6 is endlessly stretched between the pulleys. After returning the sliding doors once into totally closed positions, a wire rope fixture 8 brought out from the narrow sliding door side is fixed to the wire rope on the side with no cylindrical guide implement, and the cylindrical guide implement is connected to a fixture 9 brought out from the wide sliding door side. When moving the wide sliding door in an opening direction by the wire rope 7 on the side with the cylindrical guide implement, a first fastener 10 is fastened into an abutting position P on the side of not moving the narrow sliding door 1a, out of the cylindrical guide implement end, and a second fastener is fastened into a position Q separated in the direction of the cylindrical guide implement from the position P of the first fastener 10 by a distance obtained by adding the door width difference of the sliding doors and the length of the cylindrical guide implement, to perform the opening/closing operation of the wide sliding door.
