PROBLEM TO BE SOLVED: To prevent a film bent due to deformation over time from repeatedly contacting the frame material due to the influence of wind and rain or the like to damage the film in a vinyl greenhouse constructed by stretching a film on the frame material. thing. In the present invention, a film for a vinyl house is fixed to a frame material (2) of a vinyl house at intervals, and a film (3) is attached to each film (3) to stretch the film (3). In the fastener (1), the film (3) is framed by the bending of the film (3) stretched between the fastening position for fixing the film (3) and the frame material (2) of the vinyl house. It was decided to provide a gap forming portion (8) that does not come into contact with the material (2). [Selection diagram] Fig. 1【課題】骨組材にフィルムを張設して構成されるビニールハウスにおいて、経時的変形によって撓んだフィルムが風雨などの影響で骨組材に繰り返し接触してフィルムが破損してしまうのを防止すること。【解決手段】本発明では、ビニールハウスの骨組材(2)に間隔をあけて固定され、それぞれにフィルム(3)を止着することでフィルム(3)を張設するためのビニールハウス用フィルム止着具(1)において、フィルム(3)を止着する止着位置とビニールハウスの骨組材(2)との間に、張設されるフィルム(3)の撓みによってフィルム(3)を骨組材(2)に接触させない隙間形成部(8)を設けることにした。【選択図】図1
