As shown in FIG. 6 to FIG. 6, the swelling portion 11 is formed from the outside of the swelling side by a pressing press or the like so that a mold slightly smaller than the shape of the swelling portion 11 formed in the previous process ( (Not shown), the swelling portion 11 is squeezed, and as the swelling portion 11 is squeezed, the periphery of the medium-spread slit 12 is also gradually squeezed, and finally a cutter or a punching press is used. Thus, a spray hole 9 having a desired elaborate shape that cannot be formed is formed (see FIG. 6). In the figure, reference numeral 13 denotes a positioning bulge that is simultaneously press-molded when the partially spherical bulge 11 is formed, and the positioning bulge 13 is a positioning bulge formed at the distal end of the support member 6. The spray direction of the spray hole 9 is set by fitting to the projection 14.
因みに、こうして形成された噴霧孔９は第７図に示す
