Zusammenfassung:To provide a support metal fitting for a band capable of reducing force required for driving a winding shaft, and suppressing deterioration of a sheet, when being installed on a simplified construction, and a light block device capable of reducing force required for driving the winding shaft and suppressing deterioration of a light block sheet.SOLUTION: There is provided a support metal fitting 5 as means for solving problems, the support metal fitting for supporting a band 4 is installed on a plastic greenhouse H. The greenhouse H comprises: a plurality of arch pipes P1 which is arranged in a depth direction; a light block sheet 2 for covering the arch pipes P1 from a top part to a side part; a winding shaft 3 which is fitted to a lower end of the light block sheet 2 along the depth direction of the arch pipes P1, rolls on the arch pipes P1 for winding the light block sheet 2; and a band 4 which is installed along a longitudinal direction of the arch pipes P1 and can press the light block sheet 2 from an upper side to the arch pipe side. The support metal fitting has a support part for supporting the band 4 at a position separated to an upper side from the top parts of the arch pipes P1.SELECTED DRAWING: Figure 1 【課題】本発明では、簡易構築物に設置されると巻取軸の駆動に必要な力の低減やシートの劣化の抑制を達成できるバンドの支持金具の提供と、巻取軸の駆動に必要な力の低減や遮光用シートの劣化の抑制を達成できる遮光装置の提供を目的とする。【解決手段】前記課題を解決するための手段は、奥行方向に並べて配置される複数のアーチパイプP1と、アーチパイプP1を頂部から側部にかけて覆う遮光用シート2と、アーチパイプP1の奥行方向に沿って遮光用シート2の下端に取り付けられて、アーチパイプP1上を転動して遮光用シート2を巻取る巻取軸3と、アーチパイプP1の長手方向に沿って設置されて上方から遮光用シート2をアーチパイプ側へ押さえつけ可能なバンド4とを備えたビニールハウスHに設置されてバンド4を支持する支持金具5であって、アーチパイプP1の頂部からバンド4を上方側に離間した位置で支持する支持部を備える。【選択図】 図1
