Insulated operating rod and its manufacturing method

The present invention provides a method of manufacturing the insulated operating rod between a ceramic and a metal member can be a good sealing contact. The insulation operation rod-based method of maintaining a vacuum in a closed container and the operating force transmitting insulating, ceramic insulation operation rod and sealing the metal member, ceramic (1) and the metal part (6) of the insulating operating rod between the intermediate material (4) is provided with a Fe-Ni based alloy, copper-based composite material, carbon steel or copper and its alloys. A method of manufacturing the insulated operating rod in the present invention by the ceramic (1) and metal part (6) provided on at least one convex portion and the concave portion while heating using a hot press method with the chimeric insert and brazing thereof engaging surface sealing process.
