Abstract

In a gas turbine of the invention, a first blade ring portion to which first vanes are attached and a second blade ring portion to which second vanes are attached are integrally formed to form an integrated blade ring. A second upstream pressing member is arranged on the upstream side of a second upstream isolation ring which attaches a first ring segment and a second vane stage which is arranged on the downstream side of the first ring segment to the integrated blade ring. By attaching the pressing member to the blade ring portion, the pressing member pushes and fixes the isolation ring to the downstream side, and the sealing performance of a packing is maintained.
