PROBLEM TO BE SOLVED: To provide a triple sliding door device that utilizes existing techniques and reduces costs.SOLUTION: A triple sliding door device 1 includes a double sliding door device 8 having a rack and pinion gear structure 23 for linking a first door 2 and a second door 3, to which a third door 4 and an opening/closing-type interlocking device 9 are added to form a triple door device. The opening/closing-type interlocking device 9 comprises a pair of large-diameter driven pulleys 45, a belt 46 for the large-diameter driven pulley, a pair of small-diameter driven pulleys 47, a belt 48 for the small-diameter driven pulley, and a pulley base 49. Also included are a connection metal fitting 50 on the third door side linking a third hanging metal fitting structure 37 with the belt 46 for the large-diameter driven pulley, and a connection metal fitting 51 on the second door side linking a second hanging metal fitting structure 22 with the belt 48 for the small-diameter driven pulley.SELECTED DRAWING: Figure 2 |
