| 摘要 |
The present invention relates to an electric louver system. More particularly, slats are easily opened or closed by integrally rotating the gears of a head gear, which are engaged with a rotation shaft mounted on a guide rail, by the rotation force of the rotation shaft. The head gear, which is lifted by a lift, may be returned to a precise position via an interval keeping plate at the time of lowering, thereby generating no clearance among the slats. |
