PURPOSE: A natural ventilation system for a window is provided to prevent interference with a slider, which is an opening and closing control unit, even if a finishing panel is extended to an end cap. CONSTITUTION: A natural ventilation system for a window comprises end caps(200). Each end cap comprises a housing, an operation cam, a stopper, and a slider(250). The housing has an operation space. The operation cam is located at the operation space of the housing. A pinion gear is formed on the outer surface of the operation cam located at the operation space, and a part of the operation cam exposed to the outside the housing is connected to a flap(130). The stopper is installed around the operation cam and fixes the operation cam. The slider is inserted into the operation space through the bottom of the housing. When the slider is operated, the operation cam rotates the flap, and a ventilation opening is opened and closed. |
