    • PROBLEM TO BE SOLVED: To enable a dweller to safely take refuge by constituting a frame body to install a steel door out of an inner frame and an outer frame, arranging a deformation absorbing mechanism actuated between them only at time of big earthquake, and maintaining an opening/closing function of the door even if a building frame is deformed. SOLUTION: A door outer peripheral frame 2 of a steel door 4 of a multiple dwelling house of a reinforced concrete structure, is doubly constituted of an outer frame 2a and an inner frame 2b, and is connected by a sliding mechanism 3 by arranging a sufficient clearance C between them. This sliding mechanism 3 is fastened by a bolt through a spring washer by superposing loose holes arranged in a plate-like part 2a' of the outer frame and a plate-like part 2b' of the inner frame, and is actuated only when earthquake external force not less than a certain magnitude is applied, and a deformation absorbing function operates. Even if a building frame 1 is deformed, its deformation is absorbed by the outer frame 2a, and influence is not exerted on the inner frame 2b, and the door 4 can be easily opened/closed and locked. Therefore, even in big earthquake, a dweller can safely take refuge, and a burglar-proof function can also be maintained.
