<p>PROBLEM TO BE SOLVED: To provide a vinyl greenhouse in which strength to force that acts in a vertical direction to a ridge direction of the vinyl greenhouse can be enhanced.SOLUTION: A vinyl greenhouse H comprises a frame 1 and a vinyl sheet stretched by the frame 1, wherein the frame comprises a plurality of outer frames 10, 10... aligned in a ridge direction and one or more lateral pipes 11 which extend in the ridge direction and connect the outer frames 10. The vinyl greenhouse comprises inner frames 2 arranged inside the outer frames 10 and a plurality of oscillation axes 3, 3... interposed between the outer frames 10 and the inner frames 2 oscillatingly in their respective axes' direction and is configured that when force shifting the outer frame 10 and inner frame 2 in the axial direction acts, force in a tensile direction is inputted to one or more of the oscillation axes 3, 3..., and force in a compression direction is inputted to the other one or more of the oscillation axes 3, 3....</p> |
