Zusammenfassung:	PURPOSE:To improve the turbine efficiency by forming a band-shaped projection extending in the circumferential direction between the outer peripheral surface of a precut shroud formed integrally with a movable vane body and the inner peripheral surface of a connecting shroud. CONSTITUTION:A precut shroud 25 and a tennon 23 are integrally installed in projection at the top edge part of a movable vane body 22. A connecting shroud 24 is inserted into the tennon 23, and the connecting shroud 24 is fitted by caulking the tennon 23. A band-shaped projection 40 is formed in the circumferential direction between the outer peripheral side of the precut shroud 25 and the connecting shroud 24. Therefore, leak of steam can be prevented, and the turbine efficiency can be improved.
