Claims (1)

[Claims for Utility Model Registration] (1) A robot in which a plurality of operating shafts connected in series are individually rotated, and a work is performed by a working machine disposed on the operating shaft at the tip. An energizing device that supplies electric power for operating a machine, comprising: a rod-shaped energizing bar with high electrical conductivity, one end of which is relatively rotatably attached to one of the plurality of operating shafts; and the energizing bar. a support member that is relatively rotatably attached to an operating shaft different from the operating shaft to which the bar is attached and supports the energizing bar so as to be movable in the axial direction; a support member that is provided at the one end of the energizing bar; a first connecting means for connecting an energizing member for energizing the electric power to the part; and a first connecting means disposed on the support member for energizing the electric power to the energizing bar while allowing movement of the energizing bar in the axial direction. and a second connection means for connecting the current-carrying member of the robot, and the power is supplied through the current-carrying bar. (2) In a robot in which a plurality of operating shafts connected in series are individually rotated and work is performed by an operating machine installed on the operating shaft at the tip, electric power is supplied to operate the working machine. An energizing device for supplying electricity, comprising: a pair of rod-shaped energizing bars with high electrical conductivity, each of which has one end relatively rotatably attached to a different operating shaft among the plurality of operating shafts; and the pair of energizing bars. a connector that connects the other end portions so as to be relatively rotatable and electrically connects them; and a connector provided at one end portion of the pair of current-carrying bars, and connecting a current-carrying member for energizing the electric power to the one end portion. A power supply device for a robot, comprising: a pair of connecting means, and the power is supplied through the pair of power supply bars.
