Abstract
It is an object of the present invention to provide a compressor that has a simple structure, produces a damping effect and improves aerodynamic performance. In a compressor including stator bladescircumferentially mounted to an inner circumferential surface side of a casingforming a annular path; and an inner barrelsupported by the casing and arranged on the radially inside of the stator blade as a partition wall on the radial side of the annular path; the stator blade includes an outer shroudmounted to an inner circumferential surface of the casing at a position facing the inner barrel, and an inner shroudsupporting a blade portion at an inner diameter side, the inner shroud being disposed in an annular groove formed in an outer circumferential surface of the inner barrel facing the inner shroud. The stator blade including the outer shroud, the inner shroudand the blade portionsare formed in a monolithic structure by milling.
