A sealed packing structure is provided to enable use of a difficult material to be used due to lack of resiliency even though its use is requested for chemical stability. A sealed packing structure includes a lower packing part(51) and an upper packing part(52). The upper packing part has a hollow part(53). At least a half of the lower packing part is accommodated in a groove of a door. The lower packing part has a solid structure to receive a pressure against the groove of the door. The upper packing part has the hollow part for providing flexibility and elasticity. The packing structure is formed of EPDM(Ethylene Propylene Diene Monomer) or Teflon. |
