연소기용 통체(12)는 통 본체(21)와, 통 본체(21)에 형성되는 제1냉각 통로(22) 및 제2냉각 통로(23)와, 공급구 연설부(30)를 구비한다. 제1냉각 통로(22)는 통 본체(21)의 외주면(21c)으로 개구하는 공급구(25A)를 가진다. 제2냉각 통로(23)는 공급구(25A)보다도 하류 측에서 통 본체(21)의 외주면(21c)으로 개구하는 배출구(27)를 가진다. 공급구 연설부(30)는 공급구(25A)와 배출구(27) 사이에서 통 본체(21)의 외주면(21c)으로부터 연장하는 제1벽부(31) 및 공급구(25A)보다도 상류 측에서 통 본체(21)의 외주면(21c)으로부터 연장하는 제2벽부(32)를 가진다. A cylinder for a combustor provided with a cylindrical member, a first cooling passage and a second cooling passage formed in the cylindrical member, and a supply port extended portion. The first cooling passage includes a supply port that opens to an outer peripheral surface of the cylindrical member. The second cooling passage includes a discharge port that opens to the outer peripheral surface of the cylindrical member downstream of the supply port. The supply port extended portion includes a first wall portion disposed between the supply port and the discharge port extending away from the outer peripheral surface of the cylindrical member and a second wall portion disposed upstream of the supply port extending away from the outer peripheral surface of the cylindrical member.
