However, in the conventional sliding window, if a high wind pressure of 1500 Pa, for example, acts on the window during a typhoon, the shoji will be pushed into the room by the wind pressure. In this case, the airtight material is crushed by being installed on the guide piece on the outdoor side of the upper frame, and the guide piece on the outdoor side approaches the indoor side until it hits the guide rail. There will be a gap between them. Therefore, there is a problem that a strong air flow is generated through the gap formed on the indoor side of the guide rail, and water enters the indoor side together with the air.
