[Problems to be solved by the device]

 Conventionally, this type of ceiling louver has been required to have a simple structure, a light weight, and a low cost, and therefore, a single power source is often used. The method of opening and closing a large number of blades with a single power source includes a method of driving only the connecting mechanism at one end of the blades with a power source, and a method of driving the power source in the longitudinal direction of the horizontal frame. A method has been proposed in which it is placed in the middle and both connecting mechanisms at both ends of the blades are driven simultaneously from this power source. However, in the former method, it becomes necessary to increase the rigidity of the blades, and the weight of the ceiling louvers increases. Also, in the latter method, since power is transmitted from a single power source in both vertical frame directions, a gear mechanism consisting of a gear train, bearings, holders, etc. is required, which complicates the structure and increases costs. Becomes The present invention has been devised in view of the above circumstances, and an object of the present invention is to provide an opening / closing structure for a ceiling louver that can simplify the structure, reduce the weight, and reduce the cost. .
