Provided is a rotary fireproof door in which a gap extending from the heated side to the non-heated side is eliminated. A fireproof door (10) is provided with a two-wing fireproof door body (1) and a frame body (2). The fireproof door body (1) can open and close an opening (1h). The frame body (2) surrounds three sides of the fireproof door body (1). An upper rotation shaft (3) rotatably connects to a frame body (21f). The rotation shaft (3) comprises a bearing section (31) and a boss (32). The fireproof door (10) is configured in such a manner that a first doorstop (21s) and a second doorstop (22s), the first and second doorstops (21s, 22s) being capable of coming into contact with one surface or the other surface of the fireproof door body (1), are continuous with the bearing section (31), and therefore a gap extending from said surface of the fireproof door body (1) to the other surface thereof can be eliminated. |
