PROBLEM TO BE SOLVED: To open a sliding door by the detection of smoke when a fire occurs, allow the smoke to escape to the outside of a room where the fire occurred, and also minimize such an event that flame produced by combustion according to the burning of the room where the fire occurred comes into a room adjacent to the room where the fire occurred and the fire is expanded. SOLUTION: This sliding door device is formed so that a sliding door 1 is opened by operating an opening direction energizing device 14 with a smoke detector for detecting the smoke produced by fire. Because the smoke is escaped to the outside of a room, people in the room are suppressed to suffer by inhaling the smoke. Also, a closing direction energizing device 18 is operated by a heat detector for detecting a high temperature heat produced after the smoke due to a combustion by the fire is operated so as to close the sliding door 1 so as to suppress that, according to the combustion of the room, the fire produced by combustion enters into an adjacent room and the fire is expanded. |
