PURPOSE: A roller for windows is provided to smoothly slide the window in a curved window frame. CONSTITUTION: Plural windows are established at a window frame(1) to be slid for being opened by overlapping to each other while removing a roller at one side of the window in an opening unit(2) formed at one side of the window frame. A locking guider(7) is installed in the rim of the window for guiding a center of rotation in a hinge type while opening the window. The locking guider forms a slide groove(5) at the center of the upper and the lower sides of the window frame, and plural locking grooves(6) of pin rotation are formed at the upper and the lower parts of perpendicular direction in the slide groove. |
