PROBLEM TO BE SOLVED: To enable fitting of thin rails 5 for guiding a door roller 15 of a sliding door 10 without using a connecting member, so as to reduce cost and also facilitate installation by simplifying a cutting process at an installation site.SOLUTION: There is provided a rail set in which two rails 5 and an installation jig 20 for installing the rails 5 on a floor F at a prescribed interval are combined. Two recessed strip parts 21 are formed on a rear surface of the installation jig 20 at the same interval in between as that between the rails 5, the recessed strip parts being capable of accommodating the rails 5 in a same way as when fitting the rails on the floor F. The installation jig 20 has a screw insertion hole 22 formed, into which an entire screw S for fixing the rails 5 on the floor F may be inserted. The rails 5 are positioned on the floor F while having the rails 5 fitted in the recessed strip parts 21 of the installation jig 20, the rails 5 are fixed on the floor F with the screw S inserted through the screw insertion hole 22, and the installation jig 20 is removed from the fixed rails 5.SELECTED DRAWING: Figure 5 |
