PROBLEM TO BE SOLVED: To provide a triplex sliding door that can achieve cost reduction utilizing an existing technology.SOLUTION: A triplex sliding door 1 is a door formed by further adding, to a double sliding door apparatus 8 that includes a rack-and-pinion gear structure part 23 and the like and makes a first open-close door 2 and a second open-close door 3 interlock with each other, a third open-close door 4 and an open-close-type interlocking device 9 to realize a triplex sliding door. The open-close-type interlocking device 9 is formed including: a pair of large diameter driven pulleys 45; a large-diameter-driven-pulley belt 46; a pair of small diameter driven pulleys 47; a small-diameter-driven-pulley belt 48; and a pulley base 49. The open-close-type interlocking device 9 of such structure is arranged between a second rail and a third rail.SELECTED DRAWING: Figure 2 |
