PROBLEM TO BE SOLVED: To provide a compressor which provides a damping effect by a simple structure and which is increased in aerodynamic performance.SOLUTION: This compressor includes a stationary blade 4 circumferentially installed on the inner peripheral surface side of a casing 6 in which an annular flow passage is formed and an inner barrel 7 which is supported by the casing and disposed radially inward of the stationary blade as a partition wall on the inner diameter side of the annular flow passage. The stationary blade includes an outer shroud 10 mounted on the inner peripheral surface of the casing at a position where the outer shroud faces the inner barrel and an inner shroud 11 which supports a blade part on the inner diameter side. The inner peripheral shroud is disposed in an annular groove formed in the outer peripheral surface of the inner barrel facing the inner peripheral shroud. The stationary blade formed of the outer shroud 10, the inner shroud 11, and the blade part 9 is formed by cutting integrally. |
