PROBLEM TO BE SOLVED: To provide an automatic sieving device improving the operating efficiency by effectively detaching the powder particles sticking in the pores of the sieving device when particles of a raw material powder having a sharp broken section and tending to cause choking are sieved, being capable of improving the sieving precision, and allowing easy maintenance. SOLUTION: Protrusions in contact with a sieving net are arranged on the bottom surface of a mold. Wheels capable of rotating in the moving direction of the sieving base are arranged around the lower part of the bottom surface. A large-diameter wheel having a diameter 1.2-2 times that of the above mentioned wheels is disposed at the center of the intermediate position of the above-mentioned wheels in the moving direction of the sieving base.
