PURPOSE:To prevent the generation of backlash between shafts by integrally forming a peripheral projection part onto a coupling body. CONSTITUTION:The outer peripheral surface 11 of a fastening member 10 is freely inserted into the inner periphery of a coupling body 1, and a fastening member 5 is inserted into the fastening member 10, and the conical aslant surfaces 12 and 16 of the both are lightly attached. The edge parts of the shafts 23 and 24 are inserted into the fastening member 15, and a fastening bolt 25 is inserted into the through hole 19 in a flange part 18 and screwed into the tapped hole of a flange part 3, and then the diameters of the fastening members 10 and 15 are increased and reduced respectively. Therefore, the inner peripheral surface 17 of the fastening member 15 is attached under pressure onto the outer peripheries of the shafts 23 and 24, which are fixed for the coupling body 1, free from being revolved. |
