<p>PURPOSE: To rotatably couple a coupling part between coupling members through a simple fastening element, such as a bolt and nut, in such a state that no gap (no backlash) is provided between the element and the insertion hole of the coupling part. CONSTITUTION: An insertion hole 9 for coupling is formed in a coupling part between two coupling members 1 and 2 in such a state to be inclined and eccentrically positioned and opened concentrically to a bolt 5 inserted in the insertion hole. A taper washer 8 is inserted as an eccentric load means between the two coupling members 1 and 2 and by eliminating a gap between the bolt 5 and the opening part 9a of the insertion hole 9, the coupling members 1 and 2 are rotatably fastened and coupled by means of a bolt 5 and a nut 6.</p> |
