Abstract

PURPOSE:To decrease rotating resistance of a blade body and to enhance its efficiency by coating surfaces of the blade body, which is mounted to a rotary shaft rotating in fluid, with a resin layer having small resistance of friction for the fluid. CONSTITUTION:A centrifugal fan 20 provides the first and second fan plates 21, 22 and plural fan blades 23. Surfaces of the first and second fan plates 21, 22 are coated with a resin layer S having resistance of friction for air smaller than that of an aluminum material providing material quality of these fan plates. The resin layer S is formed by blasting or applying fluorine contained resin, coating also surfaces of the fan blades 23. In this way, efficiency of a blade body can be enhanced by enabling its rotating resistance to be decreased.
