The present invention is able to reliably prevent the bending deformation of the diamond wire mesh, to provide a simple proof beast fence to easily perform the demolition work and assembly work in small groups. Equipped with A plurality of post unit 10, and Doensao 20 that was passed over in between the post unit 10 adjacent the top, and the diamond wire mesh 30 formed wound around a plurality of column lines , the thickness of the top upper side of the winding of the diamond wire mesh formed larger than the thickness of the other winding, between a pair of post unit that both ends of the Doensao which was inserted into the top upper side of the mesh of the diamond wire mesh, adjacent to laterally placed and stretched braces 40 between the intermediate portion of the head and Doensao 20 of elongated portion 14 formed on the upper portion of the strut body.FIELD 1【課題】菱形金網の撓み変形を確実に防止できて、組立作業と解体作業を少人数で簡単に行える簡易防獣柵を提供する。【解決手段】複数の支柱ユニット10と、隣り合う支柱ユニット10の上部間に掛け渡した胴縁竿20と、複数の列線を巻き掛けて形成した菱形金網30とを具備し、菱形金網の最上辺の巻線の厚さを他の巻線の厚さより大きく形成し、菱形金網の最上辺の網目に挿通した胴縁竿の両端部を、隣り合う一対の支柱ユニットの間に横架し、支柱本体の上部に形成した余長部14の頭部と胴縁竿20の中間部との間にブレース40を張設する。【選択図】図1
