PROBLEM TO BE SOLVED: To realize a barrier-free condition while suppressing increase of cost, realize a structure capable of improving beauty of the appearance and preventing foreign matter from dropping, and facilitate mounting and dismounting work of glass sliding doors 2a, 2b on/from a window frame 1 while ensuring sealing property. SOLUTION: A device provided with lower part guide rails 14a, 14b on an upper face as a lower frame 4 is used. Upper end fringes of the lower part guide rails 14a, 14b are positioned at lower positions than a part where a person and an object move among upper faces of the lower frame 4. By covering a part which is not covered with glass sliding doors 2a, 2b at an upper end opening of recessed parts 15a, 15b where each lower part guide rail 14a, 14b is provided with cover belts 24a, 24d, beauty of the appearance is improved and dropping of foreign matter is prevented. A guide member 26a provided with a guide channel 25a guiding indoor side fringes of the cover belts 24a, 24d and a seal lip 27 is integrally constituted, and distance h among the upper face of the lower frame 4 and lower end fringes of suspended wall parts 23a, 23b is reduced.
