PROBLEM TO BE SOLVED: To provide a transition piece wherein combustion vibration is hardly generated, in the transition piece of a gas turbine combustor. SOLUTION: A throttle part 35 is arranged on a transition piece inner cylinder 32. Most of a pressure wave 39 incident from a combustion chamber 7 is reflected by a compression flow passage 34, a pressure wave incident to a spot situated downstream from the throttle part 35 is reduced to extremely a part thereof and most of a reflection pressure wave returning to the combustion chamber 7 forms a pressure wave irregularly reflected by the compression flow passage 34. Thus, any specified resonating wavelength is not present and combustion vibration is hardly generated.
