Zusammenfassung:PROBLEM TO BE SOLVED: To provide a joint structure between a lower nozzle and a nozzle for casting, in which even when a crack is caused at the lower nozzle, the air from the outside is hardly advances into a nozzle hole through the crack. SOLUTION: In the joint structure between the lower nozzle 3 joined to the lower part of the lower plate 2 in a sliding nozzle device and a nozzle 4 for casting joined to the lower part of the lower nozzle 3, the inside diameter of the nozzle hole 4a of the nozzle 4 for casting is made smaller than the inside diameter of the nozzle hole 3a of the lower nozzle 3.
