To prevent the residence of a powder by eliminating the gap between the inner and outer frames of a stacking-type sieve frame for sieving wheat flour to thereby prevent a stored product insect from propagating.

This sieve frame for a particulate sieving machine comprises an inner frame 3 and an outer frame 2. The outer frame 2 is a rectangle which comprises four sides consisting of two side frame members 14, 15 and other two side frame members 16, 17, and into which the inner frame can be fitted. At the sides of the frame members 14, 15, openings 18, 19 for fine powder falling, through which a fine powder filtered by a sieve net 12 of the inner frame 3 passes, are formed. At the one side of the other two side frame members 16, 17, an opening 25 for coarse particulate falling which fits to an opening 8 of the inner frame 3 for coarse particulate falling for causing coarse particulate remaining on the sieve net 12 of the inner frame 3 to fall down, is formed. In addition, in the outer frame 2, an inclined road surface 26 which guides the fine powder to the openings 18, 19 for fine powder falling is formed while leaving behind the openings 18, 19 for fine powder falling and the opening 25 for coarse particulate falling.
