ABSTRACT:
In a cylindrical sieve, a first frame7is provided with a first ring plate7aarranged in a radial direction and a ring plate7bextended inward in an axial direction X of the sieve from an inner end of the first ring plate7a. The ring plate7bhas an inwardly warped end. A ring projection2ais fit in a ring-shaped cavity K1defined by a ring recess10aand the first frame7. The ring plate7bpresses the ring projection2aoutward in the radial direction to prevent the ring projection2afrom being slipped off the matching recess. Through holes7c(counter bores) are formed in the first frame7along the axial direction X. Four of the through holes7care used to fasten the rods6and receive the Phillips head screws6fseated therein, and the remaining through holes7creceives Phillips head screws20(seeFIG. 1) seated therein for reinforced linkage of the first frame7with the holder frame11.
