Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a shroud for a turbo machine reducing air leak into a high temperature gas passage through a gap. SOLUTION: The turbo machine (2) includes a casing (4) defining the hot gas path (12), and a shroud member (48) attached to the casing (4). The shroud member (48) separates from the casing (4) and defines the gap. The shroud member includes a first end part (76) including a first hook member (90) provided with a first seal surface, and a second end part (77) including a second hook member (95) provided with a second seal surface (97). At least one of a first and a second seal surface (92, 97) includes a plurality of labyrinth seal element (110-116) reducing air leak into the hot gas path (12) through the gap.
