Claims (1)

[Scope of Claim for Utility Model Registration] 1. An upper horizontal tube, a lower horizontal tube, a plurality of holes drilled at regular intervals in the left-right direction on the lower surface of the upper horizontal tube and the upper surface of the lower horizontal tube, and A vertical lattice tube whose upper and lower ends are fitted into an upper horizontal tube and a lower horizontal tube, and a first wedge hole and a second wedge hole that are bored in the upper and lower ends of the vertical lattice tube so as to face each other in the left-right direction. and a horizontal wedge penetrated by the first wedge hole and the second wedge hole, the upper and lower ends of the vertical lattice tube are in contact with the inner surface of the upper horizontal tube and the inner surface of the lower horizontal tube, respectively, and The wedge hole has approximately the same diameter as the horizontal wedge, and the second wedge hole has a longer dimension only in the vertical direction than the first wedge hole. A fence characterized in that the drilled fitting holes are elongated holes that are longer only in the left-right direction than the left-right outer shape of the vertical lattice pipe. 2. The vertical lattice pipe according to claim 1, wherein the first wedge hole and the second wedge hole are formed in such a manner that a horizontal wedge having a medium inclination angle from horizontal can pass through the first wedge hole and the second wedge hole. 3. A vertical lattice pipe according to claim 1, wherein the first wedge hole and the second wedge hole are formed in such a manner that a horizontal wedge having a medium inclination angle to a large inclination angle can pass through the first wedge hole and the second wedge hole. . 4. The vertical lattice pipe according to claim 1, wherein the first wedge hole and the second wedge hole are formed in such a manner that a horizontal wedge having a large inclination angle from the horizontal can pass through the first wedge hole and the second wedge hole.
