PROBLEM TO BE SOLVED: To provide a gas turbine engine which inhibits an outlet guide vane of a compressor from vibrating while allowing the same to thermally expand.SOLUTION: The outlet guide vane 40 is arranged on the downstream side of the compressor 3 and the outlet guide vane 40 is supported at the radially outer end by an outer casing 15 and at the inner end by an inner diffuser 21, respectively. A recess 50 hollowed radially inward is formed in the outer peripheral face of the inner diffuser 21 and a locking groove 56 hollowed backward is provided in the recess 50. A guide vane inner flange 44 lying in the recess 50 is formed in the radially inner end of the outlet guide vane 40 and a locking piece 48 to be locked to the inner diffuser 21 is formed on the guide vane inner flange 44. The locking piece 48 has an extension portion 48a extending radially inward from the guide vane inner flange 44, and a locking portion 48b projecting backward from the front end of the extension portion 48a. The locking portion 48b is locked in a locking groove 56 provided in the recess 50 during operation. |
