This stator blade segment is provided with: an outer connection member extending in the circumferential direction and connecting stator blades; positioners for positioning end stator blades at the outer connection member, the end stator blades being stator blades among the stator blades and being located at both ends in the circumferential direction; and radially restraining sections for restraining the outer connection member relative to at least one of the stator blades so that the outer connection member cannot relatively move to the outside radially of a stator blade ring. The stator blades have stator blade bodies and outer shrouds. The outer shrouds have formed therein grooves which are interconnected with each other with the stator blades arranged side by side in the circumferential direction and which the outer connection member enters. Perforations, through which the positioners are inserted, are formed in the portions of the outer connection member which enter the grooves of the two end stator blades. Holes, into which the positioners having been inserted through the perforations are inserted, are formed in the bottoms of the grooves of the two end stator blades. Either one and/or the other of the positioners is an eccentric positioner having a first solid cylinder section and a second solid cylinder section which is eccentric from the axis of the first solid cylinder section. |
