PROBLEM TO BE SOLVED: To promote reduction of parts count of an oscillation sorting shelf and reutilization of of materials of the oscillation sorting shelf and a first shelf top plate and a second shelf top plate. SOLUTION: In the thresher in which a threshing cylinder 31 is provided in a state held on a shaft in a threshing chamber 33 and a material to be treated dropping down from a threshing net 30 on the lower side of the threshing chamber 33 is received by an oscillation sorting shelf 38 and oscillated and sorted while oscillating and transporting the material to be treated, a winnower 43, a first spiral 46 and a second spiral 47 are arranged in the order from the upper part in the sorting air feed direction below the oscillation sorting shelf 38 and the oscillation sorting shelf 38 is composed of a synthetic resin and the first shelf top plate 53 of the first spiral 46 and the second shelf top plate 54 of the second spiral 47 are each composed of a synthetic resin and constituted integrally with the oscillation sorting shelf 38.
