<P>PROBLEM TO BE SOLVED: To obtain a coupling device coupling a joint where a mount hole is formed with a shaft press-fit in the mount hole of the joint, and preventing the backlash of the joint relative to the shaft. <P>SOLUTION: The coupling device is equipped with: a pin 45 which is fixed on the shaft 34, extends to pierce through in the nearly radial direction of the shaft 34, and is fit in an engaging groove 46 formed on the joint 36 fit to the shaft 34; and a screw 51 which is screwed and tightened in a screw hole 50 formed on the shaft 34 and opening on the end face 49 of the shaft 34, and whose head part 52 is brought into press-contact with the surface 53 of the joint 36. By tightening the screw 51 screwed in the screw hole 50, the pin 45 is brought into press-contact with the surface 55 of the engaging groove 46. <P>COPYRIGHT: (C)2008,JPO&INPIT |
