At this time, the shapes of the concave portion 56 and the concave portion 66 are the same, and the shapes of the convex portion 61 and the convex portion 71 are the same. Further, the shapes of the sliding groove 53, the sliding groove 63, and the sliding groove 73 are the same, and in the present embodiment, they have a stepped shape, because the pivot 14 is inserted into each sliding groove to slide. If the shape of the portion to be inserted into the sliding groove on the upper part of the shoji 10 is a simple convex shape, the sliding groove does not need to be stepped and may be a simple U-shape.

Next, the cap 80 arranged at the end portion of the upper rail 20 in the longitudinal direction will be described. As shown in FIG. 6A, a cap 80 is arranged at the end of the upper rail 20. The cap 80 has a shielding portion 81 that abuts on the end surface of the upper rail 20, and side surface portions 82 and 82 that abut on the side surface portions 51 and the side surface portions 76 of the upper rail 20, respectively. As shown in FIG. 6B, the shielding portion 81 has an insertion portion 83 to be inserted into the groove of the upper rail 20 on the surface on the side that abuts on the end surface of the upper rail 20. Since the insertion portion 83 is inserted into the groove of the upper rail 20, even if the upper rail 20 is attached to the upper surface 90 with the cap 80 arranged on the upper rail 20, the cap 80 does not fall off from the upper rail 20. Further, the cap 80 is movable in the longitudinal direction of the upper rail 20 within a predetermined length range. Further, the length of the upper rail 20 of the side surface portion 82 in the longitudinal direction is larger than the length between the upper rail 20 and the wall surface or the like that occurs when the upper rail 20 is attached between the wall surfaces or the like.

Next, a method of attaching the upper rail 20 to the upper surface 90 between the wall surfaces and the like will be described. As shown in FIG. 3, first, the first member 21 is attached to the upper surface 90 while penetrating the attachment screw into the attachment hole 58. Next, the convex portion 61 of the second member 22 is fitted into the concave portion 56 of the first member already attached to the upper surface 90, and the mounting hole is held in a state where the second member 22 is held on the upper surface 90. It is attached to the upper surface 90 while penetrating the attachment screw to 68. Finally, the convex portion 71 of the third member 23 is fitted into the concave portion 66 of the second member already attached to the upper surface 90, and the third member 23 is held on the upper surface 90 in a state where the mounting hole is held. It is attached to the upper surface 90 while penetrating the attachment screw to 78.

As described above, the upper rail 20 is composed of three members, and the members can be attached one by one, so that the weight of each member is light. Therefore, even when it is arranged on the upper surface 90, it can be held by one person without difficulty. And because it is lightweight, accurate positioning is easy. In addition, when the second and third wires are attached to the upper surface 90, the convex portions are fitted into the first and second recesses before being arranged, so that accurate positioning can be easily realized. ..

Further, when the upper rail 20 is arranged on the upper surface 90 between the wall surfaces and the like, the end face of the upper rail 20 cannot be seen if the cutting length of the upper rail 20 matches the dimensions between the wall surfaces and the like. However, it is difficult to cut the upper rail 20 to the same length as between the wall surfaces and the like. If it is too long, it will not fit between the wall surfaces and the wall surface may be damaged during installation. Therefore, the upper rail 20 has to be cut short. As a result, when the upper rail 20 is arranged on the upper surface 90, a gap is generated between the end portion of the upper rail 20 in the longitudinal direction and the wall surface or the like, which spoils the aesthetic appearance. However, the upper rail 20 of the present embodiment has a cap 80, and the upper rail 20 having the cap 80 arranged on the end surface is arranged between the wall surfaces of the upper surface 90, and then the cap 80 is moved to the wall surface. , The gap between the wall surface and the end face of the upper rail 20 can be closed. The cap 80 may be arranged on both end faces of the upper rail 20, or may be arranged on only one side, and the end faces of the upper rail 20 without the cap 80 may be brought closer to the wall surface to bring the upper rail 20 and the wall surface. After arranging so as to eliminate the gap, the gap formed on the other end surface of the upper rail 20 on which the cap 80 is arranged may be closed by moving the cap 80. As described above, it is possible to realize accurate positioning with a small amount of manpower between the wall surfaces of the upper surface 90, and to arrange three rows of upper rails which are excellent in aesthetics because the gaps are closed when they are attached.

(Embodiment 2)
In the first embodiment, a mode in which the grooves for moving the sliding doors are in three rows has been described, but in the present embodiment, a mode other than the three rows will be described.

As described in the first embodiment, the recess 56 of the first member 21 and the recess 66 of the second member 22 have the same shape. Further, the convex portion 61 of the second member 22 and the convex portion 71 of the third member 23 have the same shape. As a result, both the convex portion 61 and the convex portion 71 can be fitted into the concave portion 56. Further, both the convex portion 61 and the convex portion 71 can be fitted into the concave portion 66.

From this, when the first member 21 and the third member 23 are fitted as shown in FIG. 4C, an upper rail having two rows of sliding grooves can be realized. Further, when the first member 21, the two second members 22, and the third member 23 are fitted as shown in FIG. 4 (D), an upper rail having four rows of sliding grooves is realized. can. Further, if only the first member is arranged as shown in FIG. 4A, an upper rail having only one row of sliding grooves can be realized.
The upper rails of the 1st to 4th rows arranged on the upper surface 90 and arranged with the shoji 10 in the present embodiment are shown in FIGS. 5A to 5D.

As described above, according to the upper rail of the present invention, accurate positioning is possible between the upper wall surface and the like with a small amount of manpower, and the gap between the upper rail and the wall surface and the like is closed when the upper rail is attached. It is possible to arrange upper rails with any number of rows of one or more, which is excellent in aesthetics.
