摘要

PROBLEM TO BE SOLVED: To provide the manufacturing method of diffuser capable of avoiding a waste consumption of material and reducing a manufacture cost. SOLUTION: The diffuser in which a diffuser wing and a diffuser base plate are integrally formed is manufactured by an precise casting. A gas smoothly flows into the diffuser by machining an end portion and a neighborhood at a gas flow into side of a diffuser wing in which an air is press-fed by an impeller wing to generate a pressure variation.
