PROBLEM TO BE SOLVED: To provide a thresher capable of improving rachis-branch treating performance, and reducing catching of grains, cut straws or the like in a threshing chamber and damage to grains.SOLUTION: A resistor projecting approximately semicircularly is formed on the upper face 16a side of a porous plate 16. For example, many leaking holes 33 are formed on the porous plate 16, and a mounting hole 37 is formed integrally with the leaking holes 33. Then, a round bar 39 is fitted into the mounting hole 37, and a part of the round bar 39 is projected approximately semicircularly to the upper face 16a side of the porous plate 16, to thereby constitute the resistor. The mounting hole 37 is arranged on the downstream side in the rotation direction B of a threshing cylinder relative to the leaking holes 33. |
