PROBLEM TO BE SOLVED: To improve durability of a fluid machine by positively reducing vibration acting on a stator blade. SOLUTION: In a turbine 13, the ring-like turbine stator blade 17 is structured by having base ends of a plurality of stator blade bodies 21 (21a, 21b) being supported by each of inside shrouds 22 (22a, 22b), and tip ends being supported by each of outside shrouds 23. A wedge damper 33 is arranged between adjacent inside shrouds 22a and 22b, and by a plate spring 35, the wedge damper 33 is made to pressure contact each of the inside shrouds 22a, 22b.
