PROBLEM TO BE SOLVED: To sufficiently secure the flame propagation property of an afterburner 23 while suppressing the weight increase of the afterburner 23 and accelerating the weight reduction of an aircraft engine. SOLUTION: A plurality of projections 41 in a triangular pyramid shape projected to the outer side are integrally formed at an interval in a diametral direction on both side edges of the diametral direction inner side part of each of radial gutters 39, the bottom surface part 41b of each of the projections 41 is directed to the downstream side, and the peak point part 41t of each of the projections 41 is directed to the width center side of each of the radial gutters 39.
