PROBLEM TO BE SOLVED: To provide a rotary machine capable of further reinforcing rigidity in the peripheral direction. SOLUTION: A stationary blade ring (7) is composed of an outer ring (5), an inner ring (6), a plurality of outer side shroud rings (8) arranged on the inner peripheral side of the outer ring (5), an inner side shroud ring (9) arranged on the outer peripheral side of the inner ring (6), and a stationary blade ring between both rings (8) and (9). Two inner side shroud elements (13) arranged in the peripheral direction among a plurality of the inner side shroud elements (13) are connected by a connection element (25) connected in the peripheral direction. The connection element (25) is mounted in a mounting channel (27) formed in two inner side shroud elements (13) across the circumferential direction. Two inner side shroud elements (13) are connected in the peripheral direction to reinforce rigidity in the peripheral direction. A divided face between adjacent inner side shroud elements (13) is tightened by a connection force in the peripheral direction, in particular, a pressing-in force. COPYRIGHT: (C)2006,JPO&NCIPI
