As described above, the direction changing portion structure of the rail for the moving wall according to the present invention includes the direction changing member 1 that connects the four, three, or two rail members 20. 1 has a butt welding structure of an aluminum extrusion mold 2 having a slit portion S opened downward, and is formed in a cross shape in a plan view, a T shape, or an L shape. Compared to the conventional direction changing member 31 formed by combining the metal block materials, the outer shape can be made compact, and the weight can be reduced. Moreover, the attachment work of the direction change member 1 can be made easy by the part which can be made lighter than before.
In addition, since each of the extrusion mold members 2 can surround the upper and lower sides and the left and right sides of the suspension vehicle 40, a structure having higher rigidity than the conventional case (all the members surrounding the upper and lower sides and the left and right sides of the suspension vehicle are separate members) can do.
Further, the direction changing member 1 can be easily formed so as to have various shapes (cross-sectional shape, T shape, L shape) when the inner end shape of the same extruded mold 2 is slightly changed. Because it is possible, it is excellent in productivity.

  Each extrusion mold 2 has a hypotenuse 3 formed at an angle of 45 degrees in plan view at the inner end, and four, three, or two extrude molds 2 so that the hypotenuse 3 is aligned with each other. , The welding distance can be made as small as possible to shorten the welding work time, and the productivity is excellent. Further, when the four extrusion mold members 2 are formed in a cross shape in a plan view, the shape of all the extrusion mold members 2 may be made the same, which is excellent in productivity.

  In addition, since the cross-sectional shape of the extrusion mold material 2 is set to be substantially equal to the cross-sectional shape of the rail member 20 connected to the outer end of the extrusion mold material 2, partial cutting or punching of the rail member 20 is performed. By doing so, the extrusion mold material 2 can be easily produced. Thereby, the use parts of the rail member 20 and the extrusion mold material 2 can be made common, and the manufacturing cost of the direction changing member 1 can be reduced.

  Further, the extrusion mold material 2 has an attachment portion 5 formed with an upwardly open dovetail groove 4 on the upper surface side, a connection piece 7 welded to the lower surface of the ceiling attachment beam 60, and a hole portion 6 of the connection piece 7. Since the direction changing member 1 is attached to the ceiling mounting girder 60 through the bolt and nut connection between the bolt 25 inserted into the dovetail and the mounting nut 26 fitted in the dovetail groove 4, it is considerably attached to the ceiling as in the past. Even if it does not approach, the attachment work of the direction change member 1 can be performed, and the work is not complicated.

  Further, since the steel band plate-like receiving members 8 with which the wheels 48 of the suspension wheel 40 are slidably contacted are disposed on the left and right sides of the slit portion S of the bottom wall portion 9 of the extrusion mold member 2, the minimum necessary amount is provided. Only the location (the location where the wheel 48 and the rolling ball 50 of the suspension vehicle 40 travel) can be reinforced, and the overall structure can be reduced in weight and strength.
