Linking device

Abstract

To prevent the eccentricity of a rotating shaft of a driven shaft with respect to the rotating shaft of an actuator.SOLUTION: A connecting device 10 connects an actuator 91 and a driven shaft 95 so that rotating axes coincide with each other. The connecting device 10 comprises a base member 20 connected to the actuator 91, a pair of grip members 30 for gripping the driven shaft 95, and a rotating member 40 rotating to the base member 20 around a rotating axis R. The base member 20 comprises a pair of guide holes 20B inserted with the pair of grip members 30, guiding movement of the pair of grip members 30, and extending along a direction obliquely intersecting with the rotating axis R. By the relative rotation of the rotating member 40 with respect to the base member 20, the pair of grip members 30 inserted into the pair of guide holes 20B can be equally moved to the driven shaft 95 side.SELECTED DRAWING: Figure 6
