PURPOSE: A door closing structure is provided to isolate noise and to block wind and to have heatproofing efficiencies. CONSTITUTION: The door closing structure comprises the steps of forming a rubber packing groove(20) and a guide groove(30) formed on the front and backside of a door contact plane(50) in a door frame(10) respectively, interposing a permanent magnet(21) longitudinally in the rubber packing groove(20) to make the front end of the rubber packing(22) exposed outward from the door contact plane(50), and interposing a permanent magnet(31) in the guide groove(30) to have the same polarity as the permanent magnet(21), so that the rubber packing(22) is projected forward by pushing a permanent magnet with the permanent magnet(31) of the guide groove(30).
