<p>The present invention relates to a window escape prevention unit to be aligned in a guide protrusion of a window frame and an upper slide groove of a sash frame installed in the window frame and to be pushed to the guide protrusion and the slide groove in order to join the top to the guide protrusion and insert the bottom into the slide groove, wherein the window escape prevention unit exposed to the outside of the sash frame is fixated by a fixating screw to move the sash frame to the fixated part and to fixate the exposed window escape prevention unit with a fixating screw. Therefore, the window escape prevention unit is easy to install; prevents the sash frame from escaping from the window frame by strong wind and the like; and improves energy consumption efficiency by making a space between the sash frame and the window frame be sealed and reducing the air flow between the indoor and the outdoor.</p> |
