PURPOSE:To obtain folding fences that are transportable in multiple-stacked state by connecting, in parallel with hinges, the upper frames of a front leg part and rear leg part, respectively formed of slender pipes bent in a portal shape. CONSTITUTION:A folding fence body is constituted of a front leg part 1 and a rear leg part 3, respectively formed of slender pipes bent in a portal shape. The upper frames 1a and 2a of the portal-shaped leg parts 1 and 2 are butted with each other in parallel, and the lower edge of the upper frames are connected with hinges 3. The upper parts of the connected parts fit each other when the leg parts are parted, enabling the fitting faces to work as a regulating instrument 4 that keeps the parting angle at a fixed value. |
