PURPOSE: To provide an operation device which can reduce the number of parts to be used and assembly manpower. CONSTITUTION: To drive an electric apparatus such as a disconnecting switch provided in a switchboard from the outside of the switchboard, a part near the center of an operation shaft 2 whose ends are machined into a proper shape is supported with two sets of bearings provided with retaining rings with prescribed intervals so that its end may be connected to the electric apparatus such as the disconnecting switch provided in the switchboard, and the other end may be connected to a handle for outside driving, and the outsides of two sets of retaining rings are supported with two sheets of thin plates 1 and 3 provided with holes for fitting onto the outside diameters of the bearings. |
