A flexible sealing material is interposed between the supporting hardware constituting the sealed chamber of the sliding portion, and a lip-type material is used in at least one part of the flexible sealing material, so that the pressure inside the sealed chamber is released from the outside. A closed type sliding nozzle characterized by having a configuration that allows air to escape. (2) Cooling fluid circulation holes are provided at required positions near the flexible sealing material of the supporting metal fittings constituting the sealed room to prevent burnout of the flexible sealing material and, if necessary, to prevent deformation of the supporting metal fittings. 2. The closed type sliding nozzle according to claim 1, wherein the cross-sectional area of these cooling fluid flow holes is 800 mm 2 or more. (3) The sealed sliding nozzle according to claim 1 or 2, characterized in that the mounting surface of the support metal fitting constituting the sealed chamber to the tundish is sealed by seal welding or a gasket.
