PURPOSE: A rotary windproof guide for a sliding window is provided to open and close a ventilation space between the rail of a window frame and a window sash, thereby improving the airtightness and thermal insulation of the sliding window. CONSTITUTION: A rotary windproof guide for a sliding window includes fixing units(10), wind-proofing units(20), rotation support units(30), opening retention units(40), and closing retention units(50). The fixing units are respectively installed at the upper and the lower portion of one side of the vertical frame of a window sash(200). The wind-proofing units rotatably installed at the fixing units open and close ventilation spaces between the rail(110) of window frames(100) and the window sash. The wind-proofing units are supported to be rotatably up and down by the rotation support units installed at the fixing units. The opening retention units retain the wind-proofing units to be open. The closing retention units retain the wind-proofing units to be closed. |
