PROBLEM TO BE SOLVED: To manufacture a combustion chamber provided with a dilution opening for optimizing an intake of an air flow, while preventing to the utmost as possible a turbulent flow and a high temperature point disadvantageous for thermomechanical perfectness and a life of the combustion chamber from being formed, as to the combustion chamber having an end wall, and a side wall 3 extended in a longitudinal direction from the end wall positioned in an upstream end M of the combustion chamber 1 to an orifice positioned in a downstream end V of the combustion chamber 1 and for delivering a flow of combustion gas, wherein the side wall 3 includes at least the one line of openings 30 for taking the air for diluting the flow of combustion gas in, in the annular combustion chamber for a turbo machine. SOLUTION: The at least one dilution opening 30 has an upstream edge projected toward an inside of the combustion chamber 1, and a downstream edge projected toward an outside of the combustion chamber 1, and asymmetric to the upstream edge as to a plane extended across the wall 3, the opening 30 has an axis directed diagonally to the wall 3, and the direction thereof is directed toward an inside 1, and is directed toward the downstream end V of the combustion chamber.
