摘要： PROBLEM TO BE SOLVED: To provide a gas turbine compressor having a gas turbine compressor casing, easily restorable, even if abrasion-damage advances in a casing side rail-shaped groove fitted with a dovetail part of a stator blade and supporting the stator blade.
SOLUTION: This gas turbine compressor has a compressor casing 59, a rotary shaft 55 arranged in the compressor casing 59, a compressor moving blade 60 arranged around the rotary shaft 55, and the compressor stator blade 61 supported by the compressor casing 59. A support structure of the compressor stator blade 61 by the compressor casing 59 is constituted of a rail-shaped groove (an expanded rail-shaped groove 7) having a cross section of a T shape arranged in the peripheral direction so as to be concentric with the rotary shaft 55 on the inside of the compressor casing 59 and a rail-shaped ring 8 having the outside fitted to the expanded rail-shaped groove 7 and arranged in the peripheral direction so that the rail-shaped groove (an inner peripheral side groove 9) fitted with the dovetail part 4 of the compressor stator blade is concentric with the rotary shaft 55 on the inside.
