PROBLEM TO BE SOLVED: To provide a window rotating around a horizontal axis that enables moment of shoji (a screen member) to be set to suit the shoji.SOLUTION: A window 2 rotating around a horizontal axis includes a window frame 10, a shoji (a screen member) 20, and a hinge. The shoji 20 has a first fitting part 235 provided in a part above the hinge, and a second fitting part 245 provided in a part below the hinge. A height position of a center of gravity of the shoji 20 is set by a center of gravity adjustment member fitted on at least either of the first fitting part 235 or the second fitting part 245. An expected position of a shaft center of the hinge is set in an expected range of the shoji 20 so that an expected position of the center of gravity of the shoji 20 is a different expected position relative to the shaft center of the hinge when the shoji 20 is closed.SELECTED DRAWING: Figure 4 |
