PROBLEM TO BE SOLVED: To prevent the fingers from being caught from both indoor and outdoor sides, by fitting a door body to a square frame and forming gaps having larger dimensions than the width of the fingers at the opposite parts of the indoor and outdoor sides of the hanging side. SOLUTION: A door body 5 is openably/closably fitted to a square frame 1 through metal hanger 3 and supported at the hanging side TM. The door front side TS is opened/closed through the hanging side TM as the base. The square frame 1 is formed of the vertical frames 11, 13 and the upper and lower frames. A curved cover 5a for a gap is integrally attached at the door front side TS. Gapsδ3 ,δ4 having a larger width than the fingers are formed between the cover 5a and the first frame body 21. Then, projections 33, 35 are formed so as to retract by gapsδ5 ,δ6 in the second frame bodies 25, 27. When the fingers are caught from the indoor side IN, airtight members 37, 39 are deformed to form a space between the door body 5 and the projections 33, 35 and further, when the fingers are caught from the outdoor side OUT, the gapsδ1 ,δ2 ,δ3 ,δ4 are hardly deformed. In this way, safety cab be improved.
