PROBLEM TO BE SOLVED: To allow a person to escape outside a room through an escape door, when a door is deformed and not opened by an earthquake and the like by providing the escape door in a part of the iron door in an exit of a fire- preventive construction. SOLUTION: An escape door 3 is attached to an iron door 6, or an exit of a fire-preventive construction for a condominium and the like, by a fitting hardware 7 and fixed by rotating a stopper and storing it in a stopper receiver 2. This escape door 3 is constituted into a trapezoidal shape and four-directional sections 4 are set to diagonal with their indoor side formed small and their outdoor side formed large. A plane 5 in contact with the escape door 3 of the door body 6 is formed diagonal with its indoor side formed small and its outdoor side formed large. When the door body 6 is deformed, the escape door 3 is thus slid to the outdoor side from the door body 6. If the door body 6 is not opened in an earthquake and the like, this constitution allows a person to escape to the outside through the escape door.
