Claims

[Scope of utility model registration request]

A single elastic metal plate is punched out by pressing so that two circles are joined together with a part of the outer periphery in common, and one of the circles is punched out in the center to form a ring shape, and the ring is A sliding contact is formed at a predetermined part of the other circle, and the center part of the other circle is formed into a dome-shaped support base, and an insertion hole is formed at the bottom of the other circle. A slider that is bent so that the other circular dome-shaped support is inserted into the center of the ring, a substrate that has a resistor pattern formed on its surface and through holes formed in predetermined parts, and a metal current collector plate having a cylindrical protrusion at a position, and the tip of the cylindrical protrusion of the current collector plate inserted into the through hole of the substrate is inserted into the insertion hole at the bottom of the support base of the slider. A semi-fixed variable resistor characterized in that the slider is rotatably supported on a substrate by inserting the slider into the substrate and caulking its tip.
