PROBLEM TO BE SOLVED: To provide an operation system of a plurality of variable stator blades 74 attached turnably in a casing of a compressor 14. SOLUTION: This system includes a plurality of levers having a proximal end part 86 and a distal end part 88. The proximal end part is connected with a stator blade corresponding to the variable stator blade to turn the stator blade around a stator blade shaft. This system includes an operation ring 84 being adjacent to the lever and surrounding the casing coaxially. The operation ring is connected with the distal end part of each lever and turns the lever when the operation ring itself rotates around a rotary shaft 26 of the compressor. The operation ring includes a pin 96 extending outward from an outer side face 92 in the radial direction of the operation ring itself. This system includes a template 90 including a slot 94 receiving a part of the operation ring pin. The slot includes such a shape that guides rotation of the operation ring around the rotary shaft of the compressor when the template moves for the operation ring. COPYRIGHT: (C)2007,JPO&INPIT
