The present invention relates to a coupling structure of a door frame and a window frame. A stopper unit, which is installed to separate between a front side frame and a rear side frame, can be moved according to the phenomenon of expansion and contraction due to the temperature or the moisture. Accordingly, the coupling structure of a door frame and a window frame can more easily prevent the stopper unit from being damaged by distortion and swelling according to the phenomenon of expansion and contraction due to the temperature or the moisture and can allow stopper unit, the front side frame, and the rear side frame to be easily assembled. |
