PROBLEM TO BE SOLVED: To provide a combuster for a rocket, restraining vibration of combustion in a simple and light-weighted structure for the purpose of heightening the efficiency of the combuster for a rocket. SOLUTION: This comubster for a rocket does not adopt a buffer blade for restraining vibration of combustion, which causes increase in weight of the combuster and lowering of combustion efficiency. Instead of the buffer blade, in a combustion chamber, among two or more inner wall shapes and inner wall material qualities, the optimum shape and material quality (multi-directional shape surface, a porous material quality surface, an axial different diameter surface, or a combination thereof) are adopted to inhibit a surface mode caused in the combustion chamber and restrain the vibration of combustion resonating with the sound of the surface mode.
