Abstract

PURPOSE: To facilitate adjustment of a clearance between a bearing and a peripheral surface of a guide shaft and an assembly operation by forming a support frame of a vertical auger in a short cylindrical shape wound to a peripheral surface of the guide shaft and tightening its lower end side by a nut. CONSTITUTION: A support frame 5 of a vertical auger formed by a metal material in a short cylindrical shape fitted so as to be wound to the outer periphery of a guide shaft 4 is inserted in an outer periphery of the guide shaft 4. A set bolt 8 is inserted through nearly vertical tightening plate parts 5c, 5c continued to lower ends of right/left slant plate parts 5b, 5b of the support frame 5. By tightening it by a nut 80, assembly for the guide shaft 4 of the support frame 5 is finished.
