Also, conventionally, as described above, due to the structure in which the hinge is exposed to the outside, there is a problem that noises are generated in the moving part when the opening and closing due to dust or rust occurs.

In addition, conventionally, there is a problem that the window is prevented from flowing in the upward direction when the window is opened, thereby hindering smooth inflow and outflow of air.

Also, conventionally, a pair of pneumatic cylinders are installed symmetrically on the window frame for each window, and the windows are opened and closed by driving the pneumatic cylinders, so that assembly and operation are not easy, installation cost is increased, In addition, there is a problem that the operating cost due to the energy consumption for opening and closing the window increases and the economical efficiency is lowered.
