PURPOSE:The titled readily handleable device having high airtightness, wherein a sealing element of a hollow, flexible, metallic film is set at a sealing face at a door of a coking chamber end of coke oven, a pressurized fluid is introduced into the element to expand the sealing element and the element is closely brought into contact with the circumference of the door. CONSTITUTION:In closing a lid of both end opening of a coking chamber of coke oven, a door frame 4 to be attached to an end of a coking chamber 1 is a hollow frame having a sealing element of a flexible metallic film 8' at a sealing face or is provided with a separate flexible metallic hollow material 8 made circularly to surround an opening peripheral edge at the sealing face of the door frame 4. A pressurized fluid is introduced into a channel 5 set along the whole length inside both vertical sides of the door frame 4 in a closed state, the sealing element is expanded and closely brought into contact with a sealing material 32 at the circumference of a door 30 to seal the coke oven in high airtightness.
