PROBLEM TO BE SOLVED: To provide an airtight container capable of being connected or separated in an airtight manner, and a container opening/closing mechanism.SOLUTION: A container opening/closing mechanism includes an opening/closing mechanism for airtight lids 2b and 3b that can parallely move in an axial direction one side or both sides of internal screws 3d and 3e connected to a double-end external screw 3c, and in which divided double-end external screws obtained by dividing the double-end external screw 3c in the axial direction enable telescopic motion while transmitting rotational force to each other, thereby to absorb deviation of a screw phase.SELECTED DRAWING: Figure 5 【課題】気密に連結・分離できる気密容器及び容器開閉機構を提供する。【解決手段】両端オネジ３ｃと結合するメネジ３ｄ、３ｅの片側または両側を軸方向に平行移動でき、また両端オネジ３ｃを軸方向に分割して分割された両端オネジが相互に回転力を伝達しながら軸方向に伸縮してネジ位相のズレを吸収することができる、気密蓋２ｂ、３ｂの開閉機構を備えた。【選択図】図５
