<p>PROBLEM TO BE SOLVED: To reduce the swirl component of leaked steam which causes vibrations of a rotary machine such as low frequency vibrations.SOLUTION: A rotary machine includes: a rotation shaft; multiple moving blades 50 which extend in a radial direction of the rotation shaft and are provided spaced away from each other in a circumferential direction; a casing 10 which encloses the moving blades 50 from the outer periphery side; and swirl guide parts 70, each of which is provided at the upstream side of a gap Gd between a tip of the moving blade 50 and the casing 10. Each swirl guide part 70 has a ring shape member 71 having a cross section shape that is uniform over the circumferential direction.</p> |
