Abstract:
1. A switchgear apparatus, comprising: a switching unit including a movable electrode and a fixed electrode, for opening/closing an electric circuit; a movable shaft extended from the movable electrode; an operating mechanism for performing, by providing driving force to the movable shaft, the open/close operations of the switching unit; a switching-unit holder for holding the switching unit and the movable shaft thereinside; and a holder supporting unit having a fixing plane member, for fixing the switching-unit holder thereonto, the switchgear apparatus characterized in that the fixing plane member of the holder supporting unit is constituted of a plurality of plates layered in the axial direction along the movable shaft and provided with layered-plate fixing-member through-holes, wherein the plates are fastened to each other by fixing-members passing through the layered plate fixing-member through-holes, and the plates are separately provided to induce friction therebetween when the plates are distorted at points between the fixing-members.
