The present invention relates to a sliding window. More specifically, if a locking device, included in the central part of a connection bar on which both window doors are overlapped, is locked, the inner window door and the outer window door are moved forward and backward respectively and attached to each other in order to seal the connection bar from the outside. As the inner and outer window doors are moved to an outer window frame of the sliding window, an outer frame of the inner window door is moved backward and an outer frame of the outer window door is moved forward. Therefore, the sliding window is capable of keeping airtightness to completely insulate a gap between the inner and outer window panels and the window frames from the outside. |
