Abstract
A transition piecein an embodiment is provided with an inner ductthrough which a combustion gas is led to a turbine partand an outer ductthat is provided so as to cover an outer periphery of the inner ductand has a plurality of ejection holesto eject air onto an outer peripheral surface of the inner ductformed therein. It is structured such that a channel cross-sectional area of a cooling air channelthat is formed between the inner ductand the outer ductand through which the air ejected from the ejection holesflows gradually decreases at an air flow downstream side rather than the portion where the ejection holesare formed, and gradually increases from a throat portionhaving the minimized channel cross-sectional area to an air flow downstream side.
