Claims

[Scope of utility model registration request]

A pair of fixed side terminals and one end of a variable side terminal having a circular hole formed in one end are molded into an insulating resin molded body having a circular mounting hole in the center, and one end of each of the fixed side terminals is molded into an insulating resin molded body having a circular mounting hole in the center. The variable side terminal is exposed to the upper surface of the body, and one end portion of the variable side terminal projects into the mounting hole of the molded body at a position below the upper surface of the molded body and with the centers of the circular hole and the mounting hole coincident. A resistive substrate is formed by integrally encapsulating the fixed side terminals, and has a resistive film adhered to the surface thereof, the exposed end portion of each of the fixed side terminals being used as an electrode, and both ends of which are electrically connected to these electrodes; None, the center part is loosely fitted into the mounting hole of the resistance board, the lower end surface is in sliding contact with the upper surface of one end of the variable side terminal, and an engaging part is formed at the lower end. A slider having a punched cylindrical portion rotatably engaged with one end of the variable side terminal directly or via an eyelet, and integrally having a contact point that slides into contact with the resistive film. In the variable resistor, an insertion groove for a flathead screwdriver is bored in the center of the upper surface of the disc of the slider, and an auxiliary groove whose radial length is shorter than the insertion groove so as to form a T-shape with the insertion groove. A variable resistor characterized by having a hole.
