The present invention relates to a louvered shutter including a rotating device of a slat and, more specifically, to a louvered shutter including a rotating device of a slat, capable of remarkably reducing manufacturing costs by manufacturing a product as each slat does not need a power source, and rotating and opening the whole slat at a maximum angle using power transmitted to a slat connection ring formed at a lower end of a power transmission shaft. The louvered shutter comprises: a guide rail having an inner space and multiple insertion holes formed on an inner wall at fixed intervals, wherein a side of the guide rail is connected to a cover and a rotation shaft of the slat is inserted into the insertion hole; a main gear body installed on the lower side of the guide rail and having a main rotation gear, a slave gear, and an interlocking gear which are interlocked with each other, wherein gears in which a bearing is mounted on the inner side are installed in a row by being connected to each other; a slave gear body connected to the interlocking gear of the main gear body and having an worm gear and a connection gear engaged with the worm gear; a driving motor connected to the main rotation gear of the main gear body and having the rotation shaft protruding downwards from the lower surface and a fixing bracket formed on the upper surface; a slat rotation unit; and the slat connected to the slat connection ring of the slat rotation unit to rotate and having the rotation shaft protruding to the outside and a rotation blade, wherein the bearing is mounted on both ends of the rotation shaft. The slat rotation unit comprises: the slat connection ring connected to the interlocking gear of the slave gear body and having a circular hole on the rear side and the insertion hole on the front side; the power transmission shaft formed lengthwise in the longitudinal direction and having connection protrusions protruding from the front side to the outside at fixed intervals and having a hole; and a safety pin fixing the slat connection ring and the power transmission shaft. |
