PURPOSE: To compensate deviation related to load in the relative angular position of a rotation body by connecting a shaft center to adjacent shaft parts at least at one end face using spring members, and eccentrically arranging the fixed points of the spring members to both connected shaft parts. CONSTITUTION: The rotation of a shaft center part 14 is going to be transmitted to adjacent shaft parts 9, 21 since spring members 16, 24 are constituted in torsional rigidity. Pins 17, 18 or 25, 26 are arranged at flanges 13, 15 or 19, 20 in such a way that return force generated in both spring members 16, 24 by the axial movement of the shaft center part 14 becomes a force pair in the same rotating direction. Torsion related to load in a driving system can therefore be compensated with extreme precision by accurately adjusting a signal generator 36. |
