To provide a door device, including a differential pressure relaxation mechanism, in which a door is constituted by a first door body and a second door body, which can solve the problem caused by a gap generated between the first door body and the second door body when only the first door body is opened when differential pressure occurs.SOLUTION: A door for opening/closing an opening is constituted by a first door body 2 and a second door body 3; the opening can be opened by an integral rotation of the first door body 2 and the second door body 3 to a first side from a state in which the opening is closed completely; in the state in which the opening is closed completely, a first portion (door-tail side aspect surface 23) extending in the height direction on the door-tail side of the first door body 2 and a second portion (door-front side aspect portion 34) extending in the height direction on the door-front side of the second door body 3 face each other in proximity; the first door body 2 can be rotated with respect to a second portion of the second door body 3 in the closed state so that the first portion is separated to the second side. The second portion (door-front side aspect 34) is provided with an inclined portion extending from the second side toward the first side to the door-front side in a plan view, to form finger pinch reducing means.SELECTED DRAWING: Figure 9 【課題】扉を第１扉体と第２扉体から構成してなる差圧緩和機構を備えたドア装置において、差圧発生時に第１扉体のみを開放させる時に、第１扉体と第２扉体との間に生じる隙間に起因する課題に対応する。【解決手段】開口部を開閉する扉を、第１扉体２と第２扉体３から構成してなり、開口部全閉姿勢から第１扉体２と第２扉体３が一体で第１側へ回動することで開口部が開放可能となっており、開口部全閉姿勢では、第１扉体２の戸尻側で高さ方向に延びる第１部位（戸尻側見込面２３）と第２扉体３の戸先側で高さ方向に延びる第２部位（戸先側見込部３４）が接近して対向しており、第１扉体２は、閉鎖姿勢にある第２扉体３の第２部位に対して、第１部位が第２側へ離隔するように回動可能となっており、第２部位（戸先側見込部３４）に、平面視において、第２側から第１側に向かって戸先側に延びる傾斜部を設けて、指挟み軽減手段を形成している。【選択図】図９
