PROBLEM TO BE SOLVED: To provide a scroll with heat transfer facilitating ribs of a gas turbine reducing a cost by a simple construction and obtaining high cooling efficiency for the scroll. SOLUTION: The scroll 4 whirls combustion gas G from a combustor 2 in the gas turbine about a rotation axis C and introduces it to the turbine 3. The scroll is formed on an outer peripheral surface with the heat transfer facilitating ribs 6A, 6B, 6C for facilitating cooling through heat transfer. COPYRIGHT: (C)2006,JPO&NCIPI
