PROBLEM TO BE SOLVED: To facilitate miniaturization of a gas extracting structure of a gas turbine engine where two lines from a compressor are extracted, a compressor outside case is cooled by introducing the extracted low temperature side compressed air into the rear side and the extracted high temperature side compressed air can be taken out in the separating direction from the compressor outside case. SOLUTION: In the gas extracting structure 51 of the gas turbine engine for extracting two lines from the compressor, an extraction port 107 for high temperature, an extraction port 105 for low temperature, an outside air chamber 55 installed apart from the compressor outside case outward, and the extraction port 107 for high temperature and the outside air chamber 55 are mutually connected. The structure is comprised of the compressor outside case and a pipe-like member 57 composed of the other member than a member constituting the outside air chamber to make it possible to cool the compressor with the low temperature extracted gas.
