PROBLEM TO BE SOLVED: To provide a door closer device of an elevator capable of silently opening and closing the door of a landing side entrance. SOLUTION: One end of a closer rope 9 is connected to a two-piece single swing type high-speed slide door 3 opening and closing the landing side entrance 2. One end of the closer rope 9 is wrapped around a guide pulley 10 installed at the door closing side end part of a header 5, and the other end of the closer rope 9 id suspended. The other end of the closer rope 9 is connected to the lower end of a three-way frame 1 through a closer spring 12. The closer rope 9 is towed downward by the elastic force of the closer spring 12.
