PROBLEM TO BE SOLVED: To provide a door device with high cut-off performance.SOLUTION: A first watertight member S1, a second watertight member S2 in four-side shapes are attached to a door frame 1, outdoor sides S100, S110, S120, S130 of the first watertight member S1 are positioned further on outdoor sides and the outside in front view of outdoor sides S200, S210, S220, S230 of the second water tight member S2, hardness of the first watertight member S1 is larger than hardness of the second watertight member S2. When a door body is closed, outer edge surfaces 215-218 of the door body 2 are pressed to the first watertight member S1, form a first watertight surface, and a peripheral edge surface of a main surface part 210 is pressed to the second watertight member S2, and forms a second watertight surface. |
