PROBLEM TO BE SOLVED: To provide a husked rice winnowing apparatus of a rice husking sorter which switches the separation sorting procedure of abortive grain to the discharge of abortive grain from the apparatus while securing sorting accuracy of abortive grain. SOLUTION: The winnowing apparatus of a rice husking sorter is composed of a hull and abortive grain sorting air passage (10b), and an abortive grain sorting air passage (10c) which are slantly installed to a husked rice winnowing box (9) in parallel, a middle falling port (32b) which is opened at the midway part of the hull and abortive grain sorting air passage (10b), and an abortive grain falling port (33) which is opened at the lower part of the middle falling port (32b) in the abortive grain sorting air passage (10c), so that the abortive grain can fall from the abortive grain falling port (33) to the abortive grain flowing down passage (34). Additionally, an opening and closing switching plate (31) is installed to the abortive grain falling port (33). When the abortive grain falling port (33) of the opening and closing switching plate (31) is in a state of opening, the midway part of the abortive grain sorting air passage (10c) is closed. Sorting air of the abortive grain sorting air passage (10c) is switched to blow air from the middle falling port (32b) to the hull and abortive grain sorting air passage (10b) of the upper side. When the abortive grain falling port (33) of the opening and closing switching plate (31) is in a state of closing, the midway part of the abortive grain sorting air passage (10c) is closed so that the abortive sorting air communicates to the terminal side.
