  The sheet fixing device disclosed in Patent Document 1 is functionally superior, but the following improvements are desired.

First, since the conventional sheet fixing device has been developed for fixing a single sheet, it is quite impossible to fix two sheets in a double tension. That is, in order to superimpose two sheets, two pressing members such as springs are required, but this sheet fixing device has a pair of left and right side frames stacked at the bottom, and in particular, one guide groove is provided. Since the horizontal bottoms of the other side frames are inserted into the formed thick horizontal bottom, the thickness in the vertical direction where these horizontal bottoms overlap is increased, and the space in the support frame is reduced. It is difficult to fit two pressing members inside.

Secondly, in the greenhouse, bands such as strings and wires are stretched around the sheet in order to prevent looseness and fluttering of the spread sheet. The stopper for hooking the band is attached to the above-mentioned sheet fixing device. There are cases where it is used, but for the same reason as described above, the space for mounting this stopper is narrow, and there is a problem that it is difficult to fix the stopper firmly.
