PROBLEM TO BE SOLVED: To reduce the friction resistance of an airtight material.SOLUTION: An airtight structure of an opening/closing door device includes a door body 10 which acts to be opened and closed along a width of an opening part, an immovable region which is continuous along the width of the opening part nearby the door body 10 at least in the closed state, and a second airtight material 80 which is supported by one of the door body 10 and immovable region. The first airtight material 80 integrally has a base part 81 fixed to the one, and a projection piece part 82 which projects from the base part 81 and comes into contact with the other to enable deflection and deformation, and has a recessed groove 82a, which is continuous in a direction substantially orthogonal to the flexing direction, on one thickness-directional side or the other side of the base part side. 【課題】 気密材の摩擦抵抗を軽減する。【解決手段】 開口部幅方向へ開閉動作する戸体１０と、少なくとも閉鎖状態の戸体１０に近接して開口部幅方向へ連続する不動部位と、戸体１０と前記不動部位とのうちの一方に支持された第二の気密材８０とを具備する開閉戸装置の気密構造において、第二の気密材８０は、前記一方に固定された基部８１と、基部８１から突出して前記一方に対する他方との接触により撓み変形可能な突片部８２とを一体に有し、突片部８２の基部側における厚み方向の一方側又は他方側に、撓み方向に対し略直交する方向へ連続する凹溝８２ａを有する。【選択図】 図２
