First device comprises linear guides arranged along the window frame in its lower part and at the top, and carriages for movement along linear guides. Window unit further comprises an open sliding casing, and the carriages of the first device are fixed to a sliding casing. Movable unit and said second device are mounted in a sliding casing and form a sliding section therewith, wherein the second device is mounted on the frame of the mobile unit, is connected to the sliding casing and is configured to bias the movable unit relative to the sliding casing. Sealing surfaces of the fixed part of the window block are made on a part of the length of the sliding section along linear guides.
