On the other hand, the exhaust window is installed in the building and is automatically opened when a fire occurs, and according to the opening of the exhaust window, the smoke and toxic gases in the building are discharged to the outside, thereby minimizing personal injury due to a suffocation accident.

In addition, the exhaust window serves to ventilate the interior of the building as it is opened and closed by a user's operation in normal times.

Such an exhaust window is pivotally opened and closed on a window frame, and is opened and closed by an opening and closing device. The above-described opening and closing device is composed of a main body installed on a window frame, a sprocket embedded in the main body, a driving motor driving the sprocket, and a chain connected to open and close the exhaust window while being engaged with the sprocket driven by the driving motor. .

However, the conventional exhaust window opening and closing device is composed of an electric type that opens and closes the exhaust window by entering and entering the chain by receiving a starting current, and the exhaust window cannot be opened and closed when the operation is inoperable due to a malfunction of the electric motor or control unit. It has limitations.

In addition, the conventional exhaust ventilation window opening and closing device has a limitation in that it is difficult to quickly discharge the toxic gas remaining indoors because it is configured to open the exhaust window of a high load by simply pushing the exhaust window outward through a chain that advances when a fire occurs.
