PROBLEM TO BE SOLVED: To facilitate assembly by reducing a suction fan as light as possible and at the same time to provide the suction fan of highly rigid constitution. SOLUTION: In the suction fan 30 forming constitutive respective parts by a synthetic resin, it annularly constitutes a reinforced plate 450 disposed between side plates, and a plurality numbers of substantially crescent-shaped fin apertures 450a are opened on the side surface of the reinforced plate 450 constituting annularly. The fan fits a plurality of fins 447c into a fin apertures 450a, and it fixes to fit the reinforced plate 450 by locating at midway section above the fin 447c of the transverse-flow fan 30.
