In a double door assembly in which first and second doors are respectively mounted to bilateral vertical frame members of a door frame in the manner that each door can swing both to the indoor side and to the outdoor side for its opening and closing, a structure of mating portions of the doors comprises a first mating frame element constituting the first door and providing a first mating surface, a second mating frame element constituting the second door and providing a second mating surface, a first mating seal member attached to the first mating surface to project toward the second mating surface and a second mating seal member attached to the second mating surface to the indoor side relative to the first mating seal member to project toward the first mating surface. The first mating seal member is adapted to contact the second mating surface when the first and second doors are closed while the second mating seal member is adapted to be apart from the first mating surface when the first and second doors are closed.

[ What is claimed is:] [1.] A structure of mating portions of a double door assembly in which first and second doors, each having a center, an indoor side, and an outdoor side, are respectively mounted to bilateral vertical frame members of a door frame so that each door can swing both inwardly and outwardly, the structure comprising:a first mating frame element constituting said first door and providing a first mating surface;a second mating frame element constituting said second door and providing a second mating surface; anda fin-shaped seal member having a front end portion and being attached to said first mating surface to project toward said second mating surface, said fin-shaped seal member being so adapted that the front end portion of said fin-shaped seal member is in pressure contact with said second mating surface when the first and second doors are closed,wherein said first mating surface comprises a portion having an indoor side and being retracted inwardly to the center of said first door and a portion protruded outwardly from the center of said first door, said second mating surface comprises a portion retracted inwardly to the center of said second door and a portion protruded outwardly from the center of said second door, and said fin-shaped seal member is attached to said inwardly retracted portion of said first mating surface and contacts said inwardly retracted portion of said second mating surface when the first and second doors are closed.
