Can also be used. In short, the present invention is configured such that the opening direction urging device 14 is operated by the smoke detector for detecting smoke generated by a fire to open the sliding door 1, so that the smoke escapes to the outside of the room. Sliding doors are controlled by operating the closing direction urging device 18 with a heat detector that detects the next highest temperature of heat generated after the smoke due to combustion by a fire. The most characteristic feature is that the structure 1 is configured to be closed so that the flame generated by the combustion as the room burns enters the adjacent room, thereby suppressing the spread of the fire.

[0017]

As described above, the sliding door device according to the present invention is constructed such that the sliding door is opened by operating the opening direction urging device by the smoke detector for detecting smoke generated by the fire. Since the sliding door is closed by operating the closing direction urging device by the heat detector that detects the high temperature heat generated next to the smoke, the smoke immediately after the fire has occurred can be detected quickly. If the sliding door is closed, open the sliding door by detecting the smoke and let the smoke escape to the outside of the room where the fire occurred, minimizing the possibility of people in the room inhaling the smoke and causing damage. In addition, it is possible to suppress as much as possible the spread of the fire due to the flame generated by the combustion entering the adjacent room as the room where the fire occurs burns.
