Abstract
A transition piece of a combustor that sends high temperature combustion gas to a turbine includes a cylindrical body wall and cooling air passages. The passages are formed in the body wall so as to extend in an axial direction thereof, and each of the passages has cooling air inlet ports opened at an outer circumferential surface of the transition piece and cooling air outlet ports opened at an inner circumferential surface of the transition piece. The cooling air outlet ports form a plurality of lines in a direction oblique with respect to the axial direction of the body wall. A first distance between a first line of the cooling air outlet ports and a second line of the cooling air outlet ports adjacent to the first line is larger than a second distance between the cooling air outlet ports adjacent to each other.
