PROBLEM TO BE SOLVED: To provide a suction fan for a thresher, obtained by forming some resin parts and engaging the obtained with some inserts to easily constitute. SOLUTION: The thresher is constituted by integrally molding a resin into a suction fan, i.e. fins 447c and a supporting plate 447b, and setting an engaging part 447d on a supporting plates 447b, wherein the fins 447c are axially long in a fan shaft 437 direction, the supporting plate 447b supports the fins 447c circumferentially around the axis of the fan shaft 437 with spaces and the fan shaft 437 element is passed through the engaging part 447d integrally rotatably. And the integrally molded products of the fins 447c and the supporting plate 447b of the suction fan can be engaged in the axis direction of the fan shaft 437 to obtain the thresher.
