The present invention relates to a sliding connection device for a semi-automatic door. The present invention is applied to a door system including two or more unit doors such as a sliding windows or a front door system to be installed on the upper part of a unit door and be easily used without requiring a user to replace the entire door system being used. Accordingly, when the outermost unit door is opened or closes, other unit doors can be linked with the door to be semi-automatically opened or closed while preventing the outside air from coming into a room through the gap between an upper rail and a lower rail to prevent the noise due to the flow of the outside air. The present invention can also ensure reliable thermal insulation to maintain optimal cooling/heating performance. |
