Thus, the moving frame can move while absorbing the displacement of the fixed frame in the direction orthogonal to the axial direction by the swing of the link. In addition, thereby, the moving slat is moved between a position where the slat is closed by alternately arranging the slat and the fixed slat on the same plane and a position where the slat is opened by overlapping the slat and the fixed slat in parallel. The slats can be opened and closed by moving between them substantially parallel to the fixed slats. Since the slat operating device is composed of an operation dial, a shaft, a rack, a pinion, a link, and the like, the cost is low. By providing a seal member between the opening of the operation unit case and the moving frame for separating the double-glazed glass side and the operation unit case side, the hermeticity inside the double-glazed glass is enhanced. When the operation unit case is detachable, when the slat operation device breaks down, the operation unit case can be removed and maintenance can be performed, so that the operation is easy.
