To provide a distributing device which can simultaneously or separately discharge powdery grain to two containers in response to necessity when the powdery grain is to be distributed to the two containers or the like from a storage tank or the like, and does not have fear that the powdery grain may remain in a discharging path.

For this powdery grain distributing device, a distributing device main body, an inverted Y-shape internal cylinder having a head-cut inverted conical shape, and a rotor are provided. In this case, the distributing device main body has two branched paths as discharging sections. The internal cylinder is arranged on the top of the branched paths in the distributing device main body. The rotor is arranged at the branching point between the branched paths and the internal cylinder in the distributing device main body. Also, the rotor switches the discharging direction of the powdery grain which is collected to the inside of the lower section of the internal cylinder and drops, and is rotated, positioned and fixed in such a manner that the powdery/granular body may be discharged to either one of the branched paths, or simultaneously to both of the branched paths.
