PROBLEM TO BE SOLVED: To fix an end wall of metal material, which can absorb displacement caused by different coefficients of expansion between an end wall of metal material and side walls of composite material in a combustion chamber. SOLUTION: An annular combustion chamber including outer and inner axially-extending side walls 26, 28 of composite material and an end wall 30 of metal material. The end wall is held in position on the outer and inner side walls by fixing means 38, 40. The fixing means pass through annular cavities 42, 44 that are designed to receive cylindrical end portions of the outer and inner side walls, and that are created between peripheral edges of the end wall and facing portions 46, 48 folded downstream. A determined amount of clearance J is provided between the peripheral edges and the facing faces of the outer and inner side walls in such a manner as to allow expansion to take place freely, in operation, in a radial direction between the end wall and the side walls.
