<p>According to the present invention, a system louver having a simple configuration, capable of securing a smooth operability, and capable of preventing safety accidents comprises: multiple louver units having louver plates, and installed in a rail on a building at predetermined intervals; louver shafts vertically installed at the centers of the unit bodies of the louver units; opening and closing units with worm wheels formed at the middles of the louver shafts; and horizontal moving units to allow the louver units to reciprocate in the length directions of the rails, wherein the worm wheels opens or closes the louver plates when engaged with worms fixed to direction change shafts connected to a direction change driving unit installed on one side of the rail. The system louver further includes torque connectors installed on the lower sides of the louver shafts, and stopping the rotations of the louver shafts and rotating only the worm wheels on the louver shafts when loads are generated in the louver plates, wherein the torque connectors have torque spacers coupled to the bottoms of the louver shafts in the connector bodies coupled to the worm wheels, transmitting power lower than or equal to a predetermined torque from the worm wheels to the louver shafts, and not transmitting power higher than or equal to the predetermined torque to the louver shafts.</p> |
