PROBLEM TO BE SOLVED: To provide a turbine and the like capable of suppressing the inflow of combustion gas between a high-pressure turbine and a baffle, even if the baffle is thermally deformed.SOLUTION: A turbine is equipped with a baffle 41 for forming a gas channel of combustion gas flowing from a high-pressure turbine 31 to an output turbine. The gas channel is formed between an inner peripheral side guiding surface P1 on an inner peripheral side and an outer peripheral side guiding surface on an outer peripheral side. The baffle 41 has an inner cylinder baffle member 42 including a conical portion 52 opposing to the high-pressure turbine 31 in an axial direction, an outer peripheral portion 51 ranging to an outer peripheral side end portion of the conical portion 52 and formed with the inner peripheral side guiding surface P1, and an inner peripheral portion 53 ranging to an inner peripheral side end portion of the conical portion 52; and a sub baffle member 44 joined to the inner peripheral portion 53. The inner cylinder baffle member 42 is provided with a thin-wall portion 61 for permitting the thermal deformation, at least on the conical portion 52. |
