Abstract
PURPOSE: To enhance the manufacturing efficiency of an inducer and lowers the manufacturing cost without necessitating the manufacturing of the mold or the like by separately manufacturing a spiral blade and a boss and thereafter uniting them integrally by means of welding.
CONSTITUTION: A boss 13 is provided so that the top portion 31 and the bottom surface 32 of a truncated cone may become in parallel with each other, and a shaft hole 33 is bored in the boss 3 so as to penetrate the center thereof. A cutting tool 8 cuts a rod material 5 until the shaft center so as to form a spiral groove 51, and thus a blade member 6 of the spiral blade 4 is formed. A small hole 44 which penetrates the blade member 6 is formed so that the blade member 6 may be easily expanded. Then, a spiral blade 4 is formed by cutting at a predetermined position. This spiral blade 4 is expanded so that predetermined pitches P1, P2 may be set between the blade plates 41, 41. And, the boss 3 is inserted in an opening 43 formed on a central line 7 of the spiral blade 4 and the fitting portion of the boss 3 and the spiral blade 4 are welded so as to form an inducer 2
