PROBLEM TO BE SOLVED: To provide a chaff discharge apparatus in a husking air sorting device preventing back flow of sending air to an air sorting part and scattering of impurities like fine husks, without deteriorating the environment around the husking air sorting device. SOLUTION: An air lock valve 44 is constituted to sequentially deliver husks downward by rotation of a rotor 43 with a rotor casing 42 in which multiple blades 43a are radially mounted. In the rotor casing 42, a slit-like air intake port 48 is axially opened with a given width on a side wall where the blades 43a of the rotor 43 rotate from the downward position to the upward position, and the air intake port 48 communicates with an air feed side of a husk air fan 46 via a dust sending pipe 50.
