PROBLEM TO BE SOLVED: To provide a combine having improved dust discharging efficiency by eliminating a dead space formed by a scraper. SOLUTION: A dust-discharging fan 30 to suck dust, etc., generated in threshing/sorting operation and discharge from the machine has a pair of fin-supporting members 438' having a circular disk form and coaxially attached to a fan shaft 437 opposite to each other, and a number of fins 436 placed between the circumferential edges of both fin supporting members 438' at intervals in circumferential direction. A bulged part 442a is formed on a pair of supporting walls 442 in a manner bulged outward in stepped form, a fan shaft 437 is laterally extended between both bulged parts 442a, stepped recesses 436c formed on the outer side of both side ends of each fin 436 are closely placed in a manner to be matched with the stepped protrusions 442b formed on the inner circumferential edge of both bulged parts 442a, and both side edges of each fin 436 are placed in the inside space 444 of both bulged parts 442a.
