Zusammenfassung:	The present invention provides a gas turbine compressor having a blade fixing means. The gas turbine compressor having the blade fixing means comprises: a compressor wheel fixed to a rotor; a plurality of blades arranged at predetermined intervals around the compressor wheel and having a root portion inserted and fixed in an insertion groove formed in the compressor wheel; a plurality of spacer members inserted between a support surface of the insertion groove of the compressor wheel and a lower surface of the root portion of the blade so as to securely fix the blade to the compressor wheel, wherein the plurality of spacer members may form a toothed portion at a portion where the space members engage with each other. 본 발명은 블레이드 고정수단을 구비한 가스터빈 압축기를 제공한다. 상기 블레이드 고정수단을 구비한 가스터빈 압축기는, 로터에 고정되는 압축기 휠과, 상기 압축기 휠의 둘레에 복수 개가 일정간격으로 배열되고, 상기 압축기 휠에 형성된 삽입홈에 루트부가 삽입되어 고정되는 블레이드와, 상기 블레이드를 상기 압축기 휠에 밀착 고정하도록 상기 압축기 휠의 삽입홈 지지면과 상기 블레이드의 루트부의 하부면 사이에 삽입되는 복수의 스페이서부재를 포함하되, 상기 복수의 스페이서부재는, 서로 맞물리는 결합부위에 톱니부가 형성될 수 있다.
