  Next, the configuration of the screen guide 50 will be described in detail with reference to FIGS. The screen guide 50 is obtained by connecting a large number of guide pieces 51 shown in FIGS. 7 and 8. Each guide piece 51 has the same shape and holds the lower ends of the screens 10 </ b> A and 10 </ b> B and the winding shaft 30. Thus, the bottom plate 51a and the standing walls 51d at both ends of the bottom plate 51a have a symmetrical groove shape with respect to the center line, and the inner surfaces of the bottom plate 51a and the standing wall 51d are the screens 10A and 10B and the winding shaft 30. It is formed in a smooth surface so that the lower end of can slide smoothly.

  In the bottom plate 51a of the guide piece 51, one end side 61a (hereinafter referred to as the front side) that is convex in the center line direction protrudes in a mountain shape at the center, and conversely, the other end side 61b of the bottom plate 51a ( Hereinafter, this is referred to as the rear surface side.) Is recessed in a groove shape opposite to the chevron at the center. And when the said one end side 61a and the other end side 61b mutually abut on the flat surface on the bottom plate 51a of the adjacent guide piece 51, it forms so that the end surface of the bottom plate 51a of both the guide pieces 51 may correspond exactly. When the guide piece 51 is connected in such a state, the screen guide 50 in FIG. 6A is formed in a state where it does not bend in the plane of the paper. Therefore, the lower end of the winding shaft 30 is held by the screen guide 50. In such a case, the screen guide 50 can maintain the strength that allows the screen to face the screen even when there is an action such as wind. Further, a convex portion 51b having a through hole 51c through which the flexible wire 54 is passed is formed in the center of the back surface of the bottom plate 51a.

  The standing wall 51d of the guide piece 51 has a form in which an outer piece and an inner piece are joined at a portion above the bottom plate 51a, and a convex portion 51e from which the inner piece protrudes on the front side of the standing wall 51d.
