Abstract
A variable resistor is constructed to prevent a slider from backwardly tilting toward a rotor and to maintain stable contact between the slider and a substrate. In the variable resistor, a rotor and a slider are provided in a case. A substrate having a collector electrode and an arcurate resistor is mounted in the lower end portion of the case. The slider includes an annular arm portion arranged to achieve sliding contact with the arcurate resistor, a substantially I-shaped arm portion arranged to contact the collector electrode, and a case portion coupled with the annular arm portion and the substantially I-shaped arm portion by a folded-back structure. The base portion extends up to the vicinity of the position corresponding to the tip portion of the annular arm portion. The rear surface of the base portion is supported by the rotor such that the slider is prevented from backwardly tilting.
