PROBLEM TO BE SOLVED: To simplify the structure, and reduce the space and cost by horizontally arranging the side connected to an elevator door of a rope or chain, turning it at the end of the elevator door device, and vertically arranging the side connected to an elastic body on the side of the elevator door device. SOLUTION: The tensile force of a spring 1 is changed from vertically to horizontally by a pulley 5 to transmit a closing force to a door 15 through a bracket 2. The closing force transmitted to the door 15 is transmitted to an interlocking rope 11 to transmit the closing force to a door 16 through a rope grasping bracket 9. According to this, the doors 15, 16 can be automatically closed as long as no external force such as an opening directional drive by a door device acts on. Since the spring 1 is vertically set on the side of the door device, and its dead weight vertically acts, it never protrudes out of the setting space. Further, since the tensile force regularly acts on the spring 1 to minimize the vibration, a guide device is dispensed with.
