Abstract

PURPOSE:To increase the efficiency of assembling work and to decrease the number of components, by fixing the coupling between a rotary cylinder and a disc on a rotating shaft with one screw on the rotating shaft. CONSTITUTION:A rotating cylinder 1 is located on a disc forced into a shaft 4 coupled with a rotor of a motor and fixed with a fixing screw 6. Thus, alternate tightening adjustment with two screws can be avoided for the cylinder 1, and since deflection adjustment is made with one screw 6, the working efficiency is increased and the number of components can be reduced.
