An object of the present invention is to provide a greenhouse that is difficult to collapse against strong winds. A “kamaboko-type” greenhouse or an “arch-shaped” greenhouse with a roof portion erected by a vinyl chloride pipe, which is a framework material that constitutes a greenhouse, is the top of both sides corresponding to the wife. A vinyl chloride pipe is connected and extended from the main building in a straight line or in an arch shape from the top to the main building longitudinal extension line direction and the ground direction, and is extended in an arch shape to the pipe that extends the horizontal frame that is the basic framework. , Fix. Even if strong wind blows vertically on the fragile surface of the greenhouse covering sheet, the surface pressure due to the strong wind is reduced by providing the surface with an inclination. [Selection] Figure 3【課題】強風に対して倒壊し難いビニールハウスを提供する。【解決手段】ビニールハウスを構成する骨組み素材である塩化ビニルパイプにより立設された「かまぼこ型」ビニールハウス若しくは屋根部が「アーチ型」のビニールハウスに対して、妻部に相当する両面の最上部から大棟長手延長線方向、かつ地面方向に向って、大棟から塩化ビニルパイプを直線上若しくはアーチ状に接続・延長し、基本骨組みである横方向フレームを延長したパイプまでアーチ状に伸ばし、固定する。ビニールハウス被覆シートの破損しやすい面に強風が垂直方向に吹き付けても面に傾斜を具備させることで強風による面圧を低下させる。【選択図】図３
