The present invention relates to an airtightness maintaining member of a sliding window having a window frame in which a guide rail is disposed; and a sash with a rail recess inserted into the guide rail assembled with the window frame to slide, which comprises a fixated member fixated at an upper and a lower end of one side of the sash and having an elastic body, and a movable member coupled to the fixed member and having a member rail recess sealing the surrounding area while being wrapped around the guide rail in a state of being inserted into the guide rail by being lifted or lowered by the elastic body. The present invention is overlapped with a wind preventing plate at an interval and blocks a gap between the sash and the window frame by being pushed when the sash is installed and being elastically restored after the sash is installed, thereby enhancing wind-proofness. |
