PURPOSE: Door frame connection structure with improved rigidity is provided to prevent a door from being deformed and loose, to reduce the weight and the cost, and to improve the combining rigidity of a door glass channel. CONSTITUTION: A front door of a vehicle comprises a door frame(2); a space part to which a door glass attached; and a door body part having a door-inner panel(41) and a door-outer panel(42). Door frame connection structure with improved rigidity connects a quadrant reinforce supporting the door frame, a door glass channel(8) guiding the vertical movements of a door glass, and a door belt-inner rail(6) disposed to the lower side of the space part. The quadrant reinforce comprises a first rectilinear part connected to the door frame and downwardly extended rectilinearly; a first bent part extended from the first rectilinear part downwardly and bent to the outside of the door and then combined to the door-outer panel; a second bent part bent from the first bent part to the inside of the door and combined to the door-inner panel and then extended downwardly in a predetermined vent shape corresponding to the door-inner panel; a second rectilinear part extended from the second bent part downwardly; and a door hinge part extended from the second rectilinear part to the side.
