PURPOSE: A combination structure for improving combining force of a door module panel and a door inner panel is provided to accurately and easily mount the door module panel, to improve combining force by supplying threads formed at the whole width of an inclined square nut to combine with a bolt, to position a mounting spot between two panels at the end of a trim line without forming a hole to the door inner panel, and accordingly to prevent the panel from unnecessarily getting large and reduce weight. CONSTITUTION: A combination structure for improving combining force of a door module panel and a door inner panel is composed of a combining member and a housing unit of the combining member of the door inner panel. The combining member includes a regular hexahedral body unit(12); a step unit(16) formed at the front upside of the body unit and slopingly bent forward; a circular combining groove(18) arranged on a plane connected to the step unit and extended downward and formed with threads; and an inclined groove(20) rectilinearly perforated from the front of lower end of the body unit to the rear thereof and inclined and extended upward. The housing unit of the combining member comprises two side units convexly protruded in the front; a contact unit extended between side units; an opening perforated to the contact unit to align the center to the combining groove of the combining member; and a settling groove having a slit groove formed above the side unit and the contact unit and a housing groove formed between the slit groove and the rear side of the contact unit.
