Generally, a window means a window or a door to be installed in an opening of a window or an entrance to block the inside of the building from the outside. Windows are classified as wooden windows and metal windows depending on the materials used, but recently, doors and window frames made of plastic are also being made.

The window has been developed in a wide variety of shapes and structures, and is divided into sliding doors and casings according to the sliding door type. The sliding door is a way to open or close a door or window by sliding it along the groove of the door frame, and the door is opened and closed by turning a door or window around the hinge.

In the sliding door made of a plurality of doors, if the doors are independently opened and closed, it is inconvenient for the user to open and close a plurality of doors one by one.

Accordingly, when one door is opened and closed, the other sliding door is opened and closed by interlocking, and a sliding door has been developed and widely used. As an example of this, disclosed in Korean Utility Model Publication No. 20-2011-0007925, entitled " Interlocking sliding door, " and recently, Korean Patent Publication No. 10-1182413 entitled "Interlocking Device for Triple Interlocking Door" A sliding interlocking device is provided on the upper side of the door so that opening and closing of the door can be easily and easily accomplished while preventing generation of noise to the utmost.
