PROBLEM TO BE SOLVED: To provide a window screen that enables a net material to be stretched over all four sides of a frame, without shielding a shoji screen with the frame even when the window screen may be fitted and removed from an indoor side.SOLUTION: A window screen 2 includes a frame 3 formed in a frame-form by assembling a pair of vertical frame members 3a, 3a and a pair of horizontal frame members 3b, 3b, and a net material 4 stretched over the frame 3. The window screen is fitted removably on a rectangular window screen fitting part 5b and a window screen fitting part 5b of a building opening part 11a installed on an indoor side of the window screen fitting part 5b and having a rectangular opening part of small inner height and width dimensions. Inner height and width dimensions of the frame are set to be greater than the inner height and width dimensions of the opening part. Either the vertical frame member 3a or the horizontal frame member 3b has a first frame 3h, a second frame 3i, and a folding member 12 connected to the first frame 3h and the second frame 3i to be rotatable in a depth direction, and folded at an intermediate part in the depth direction.SELECTED DRAWING: Figure 1 |
