4を一体化する。Here, the cylindrical protrusion 18 is processed into a substantially elliptical shape when viewed from the front by cutting both sides of the tip into a straight line. Further, the washer 23 has a hole 24 in the center wall thereof, into which the tip of the cylindrical projection 18 of the cap 17 is fitted, and the space between the cylindrical projections 18 is located close to the center wall of both side walls. The holding pieces 26 and 25 are cut and raised so that they are smaller than the middle a of the tip of the holding pieces 26 and 25. Here, the height of both side walls of the washer 23 is set so that the tip of a screwdriver can be inserted into the washer 23 and adjusted.
To assemble it, first insert the hollow eyelet 9 of the inner terminal plate 8 into the hole 4 of the resistor board 1 to which the outer terminals 7, 7 are fixed, and iron it into the notch 6 of the stopper piece 10. By sequentially fitting the seat plate 12 and the slider 14 into the hollow eyelet 9 protruding on the resistor board 1, these parts are stacked on the resistor board 1, and the hollow eyelet protruding on the upper surface of the slider 14 By caulking the tips of the eyelets 9, the resistor substrate 1, the intermediate terminal plate 8, the seat plate 12 and the sardine 1
