Claims

[Claims for Utility Model Registration] (a) A conductive fixed terminal having a tool attached to one end face while maintaining electrical insulation, and one power supply terminal for the tool being connected to the outer peripheral face; (b) The fixed terminal is mounted from the other end side while maintaining electrical insulation with respect to one end face and a through hole opening in the other end face, and the tool is attached to one end face of the fixed terminal protruding from the one end face side. (c) a conductive shaft member to which the other power supply terminal is connected and whose other end surface is attached to the end surface of the distal end of the arm of the robot while maintaining electrical insulation; (d) conductive first and second rotating terminals arranged to be rotatable relative to the outer circumferential surface, respectively connected to power cables, and electrically insulated from each other; (d) the first and second rotating terminals; The inner circumferential surface of the terminal, the other end surface of the fixed terminal, and the step end surface of the shaft member are respectively slidably contacted, and the conductive path between the first rotary terminal and the fixed terminal and the first 1. A power supply device comprising first and second sliding contact members forming a conductive path between two rotating terminals and a shaft member.
