PROBLEM TO BE SOLVED: To sufficiently prevent combustion gas from flowing toward a center of a disk from a rim part side of a front seal 61 or a rim part side of a rear seal 63 by just small quantity of cooling air flowing into a front cooling flow passage 87 and a rear cooling flow passage 95. SOLUTION: This engine is provided with a front cooling plate 85 provided on a front stationary part 69 close to a front side of a turbine disk 55, the front cooling flow passage 87 formed between an opposed surface of the front cooling plate 85 and a front surface of a rim part of the turbine disk 55, a rear cooling plate 93 provided on a rear stationary part 81 close to a rear side of a turbine disk 55, and the rear cooling flow passage 95 formed between an opposed surface of the rear cooling plate 93 and a rear surface of the rim part of the turbine disk 55.
