<P>PROBLEM TO BE SOLVED: To provide a coupling device capable of easily and firmly mounting a coupling shaft not having a slit, on an end part of the rotating shaft having a slit over the longitudinal direction from the end part. <P>SOLUTION: This coupling device is composed of the rotating shaft 1 having the slit 1-1 over the longitudinal direction from the end part, the coupling shaft 2 of a diameter same as that of the rotating shaft, and having a connecting shaft 2-1 of a small diameter fitted to a recessed part formed on the end part of the rotating shaft 1, and a connecting ring 3 having a hole of a diameter same as that of the rotating shaft on its center. The connecting shaft 2-1 of the coupling shaft 2 is fitted to the recessed part of an upper end of the rotating shaft, then the hole of the connecting ring 3 is inserted to a position of a fitting part of the rotating shaft 1 and the connecting shaft 2-1, and the rotating shaft 1 and the coupling shaft 2 are fixed by a fastening screw 4 engaged with a threaded hole formed from an outer periphery of the connecting ring 3 toward the center hole at a position approximately orthogonal to the slit of the rotating shaft. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
