PROBLEM TO BE SOLVED: To provide a combustion chamber exhibiting excellent durability against vibration generated by combustion of an air/fuel mixture. SOLUTION: This annular combustion chamber for a turbomachine is provided with inner and outer annular walls 4a coupled by a transverse-directional wall, downstream ends of the inner and outer annular walls are extended by inner and outer fixing flanges 18 to be fixed respectively to inner and outer shells 2a of a casing in the turbomachine, and the combustion chamber is thereby held in a prescribed position. A plurality of air supply holes is provided in the inner flange 18 to supply cooling air to a high-pressure turbine of the turbomachine. The air supply holes penetrated through the inner flange 18 are distributed circumferentially over at least two lines 26a, 26b arranged with alternate constitution. COPYRIGHT: (C)2006,JPO&NCIPI
