There is a problem in that parts or the like must be repaired or replaced, and replacement work (including disassembly and reassembly work) requires a lot of labor and time.

In the conventional double sliding door type fence, since a fence body is configured by incorporating a shielding member such as a vertical lattice inside the vertical frame and the upper and lower horizontal frames, the shielding member such as the vertical lattice is not used. It is impossible to change to a shielding member constituted by the decorative member. Therefore, in the double sliding door fence of the series product, if the design of the shielding member is changed halfway, even if the design of the shielding member is changed, it is impossible to replace or change only the shielding member. It is necessary to keep using the shielding member of the design.

In view of the above problems, the present invention makes it possible to easily disassemble and assemble necessary parts of the upper part without disassembling the lower part including the lower cross member and the bogie, etc. of each fence. A double sliding door type fence capable of easily repairing, replacing, or changing the design of a portion including a support, an upper cross member, and a shielding member above a lower cross member of each fence body is provided. That is the purpose.
