2. Description of the Related Art Generally, for example, in winter when indoor heating is performed, the temperature difference between indoor and outdoor becomes large.
When indoor warm air directly contacts the indoor side wall surface such as the shoji that is incorporated into the sash frame that forms the opening frame of the building window, moisture in the air is rapidly cooled and condensation occurs,
Especially in cold regions, the condensation phenomenon is severe.

However, the current situation is that the conventional measures have not taken sufficient measures to prevent such a dew condensation phenomenon.

[0004]

For this reason, the opening and closing of the shoji screen can be prevented by contaminating the curtain on the inside of the room, wetting the floor surface, or by staying in the lower part of the sash frame and freezing it with water droplets that have condensed. Make it difficult.

Also in the conventional screen door, since the door main body having the mesh member stretched over the entire surface of the single frame is slidably assembled to the sash frame, a door bag for accommodating the rain door is attached during storage. Some sash frames use the door pocket as a storage place, but if there is no door pocket, remove the door body from the sash frame and store it in a storeroom, leave it on a terrace or veranda, or leave it as it is. Since it is currently left as it is assembled in the sash frame,
I am having trouble with the storage and storage location of the screen door, especially when the screen door is left in the state of being assembled to the sash frame, dust and dirt etc. are likely to adhere to the mesh of the mesh member and stains are apt to stand out.
There was a problem of impairing the aesthetics of indoors and outdoors.
