摘要:
In a cylindrical sieve, a first frame 7 is provided with a first ring plate 7a arranged in a radial direction and a ring plate 7b extended inward in an axial direction X of the sieve from an inner end of the first ring plate 7a. The ring plate 7b has an inwardly warped end. A ring projection 2a is fit in a ring-shaped cavity K1 defined by a ring recess 10a and the first frame 7. The ring plate 7b presses the ring projection 2a inward in the radial direction to prevent the ring projection 2a from being slipped off the matching recess. Through holes 7c (counter bores) are formed in the first frame 7 along the axial direction X. Four of the through holes 7c are used to fasten the rods 6 and receive the Phillips head screws 6f seated therein, and the remaining through holes 7c receives Phillips head screws 20 (see FIG. 1) seated therein for reinforced linkage of the first frame 7 with the holder frame 11.
