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 obtained by integrally molding a resin into fins 447c and a supporting plate 447b of a suction-fan and setting an engaging part 447d on a supporting plate 447b, wherein the fins 447c are axially long in the 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 integrally rotatably passed through the engaging part 447d. And the thresher can engage the axial direction end of the fan shaft 437 of the fins 447c of the suction fan into an engaging part 448c from the axis direction of the fan shaft 437, wherein the engaging part 448c is set at the outer periphery of a fin receiver 448 engaged to the fan shaft 437 through a boss part 448a.
