PROBLEM TO BE SOLVED: To improve a combustion residual collection effect and to allow usage as a partition member for a pressure chamber by overlapping plain stitch wire gauge in the radius direction, compressing them in the radius direction and in the axial direction so as to form them into a cylindrical layered wore gauge body, and provided a specific flow rate and a specific pressure loss at an ordinary temperature. SOLUTION: A stainless steel strand is plainly stitched so as to be formed into a cylindrical body, and its one end part 2 is bent outward repeatedly, so that a ring type laminated body 3 is formed. Then, the laminated body 3 is inserted into a die so as to be compressed in the radius direction and in the axial direction, so that a loop type network in each layer is compressed and a layer is formed in the radius direction, and consequently, a clearance structure for coolant 4 is complicated. In this process, compression molding is carried out so that a pressure loss of 0.3×10<-2> -1.5×10<-2> /kg/cm<2> is obtained at a flow rate of 100l/min/cm<2> at an ordinary temperature, and as a result, an excellent collecting function can be provided in addition to a natural cooling function, while a combustion chamber for a gas generator can be divided. Consequently, a combustion chamber partition member required separately can be dispensed with and the number of parts can be lowered. |
