PROBLEM TO BE SOLVED: To provide a tail pipe structure of a gas turbine, which flows combustion gases into a turbine so that the temperature and the flow velocity thereof are uniformly distributed in the circumferential direction. SOLUTION: This tail pipe structure comprises: a plurality of tail pipes 26 arranged parallel with each other and adapted for introducing the combustion gases G from a combustor 2 into the turbine 4; and a cooling cover 7 for covering the outer periphery of the tail pipes 26 to introduce a compressed air A from a compressor 2 between itself and the tail pipes 26. A cutout part 8 recessed from the downstream end edge 7bb of the cooling cover 7 to the upstream side is formed at both side parts of the downstream end part 7b thereof covering near the downstream end parts 26b of the tail pipes 26.
