PROBLEM TO BE SOLVED: To provide a turbine wherein cat back is prevented from occurring (a turbine casing 1 is prevented from being warped in a cat-back-like shape). SOLUTION: The turbine casing 1 comprises a lower half casing 2 and an upper half casing 3 connected to each other. Projection sections 4 projecting from both ends of the lower half casing 2 are supported by columnar supports 6. Supported surfaces 4a of the respective projection sections 4 are on the same plane as a connecting plane C between the lower half casing 2 and the upper half casing 3. Surfaces of the lower half casing 2 including the projection sections 4 and the upper half casing 3 are covered with a heat insulator 10. COPYRIGHT: (C)2007,JPO&INPIT
