Abstract

See full text

A transition piece 10 in an embodiment is provided with an inner duct 20 through which a combustion gas is led to a turbine part 130 and an outer duct 30 that is provided so as to cover an outer periphery of the inner duct 20 and has a plurality of ejection holes 31 to eject air onto an outer peripheral surface of the inner duct 20 formed therein. It is structured such that a channel cross-sectional area of a cooling air channel 50 that is formed between the inner duct 20 and the outer duct 30 and through which the air ejected from the ejection holes 31 flows gradually decreases at an air flow downstream side rather than the portion where the ejection holes 31 are formed, and gradually increases from a throat portion 60 having the minimized channel cross-sectional area to an air flow downstream side.
