Claims

[Scope of utility model registration request]

A device equipped with a pulley that simultaneously opens and closes at least two smoke exhaust doors installed in the ceiling or vertical wall of each room or space in the middle of a flue installed in a building or at the end of the flue. and a cable relay means, one end of which is rotatably supported by a fixed part, one end of which is connected to a first smoke exhaust door, a middle part of which is hooked to the pulley and connected to the other end or the second smoke exhaust door. a first cable connected to the cable; a second cable whose one end side is connected to the cable relay means and rotates the cable relay unit by a predetermined angle; a bare winding means capable of winding up and unwinding the second rope and having a function of maintaining the coiled state as necessary, and driving the bare winding means to wind the second rope. A smoke exhaust door opening/closing device characterized in that the cable relay means is rotated by a predetermined amount and the pulley is moved so that at least two smoke exhaust doors can be closed simultaneously via the first cable.
