Abstract

Large-diameter part 16 is formed at the axial-middle part of rotary shaft 15 that rotates driven by operating device. Insulated operating rod 14, the distal end of which makes move in the form of a segment of a circle effected by the rotation of rotary shaft 15, is formed integrally using filler-filled resin over large-diameter part 16 of rotary shaft 15 by cast so that the large-diameter part 15 is embedded into one end of insulated operating rod 14. The contact and connection between insulated operating rod 14 and moving rod 13 is given such sliding surface 21 as is formed for example in an elliptical shape so that the contact occur always at almost one-point on the axis line of the moving rod 13.
