ABSTRACT:
A variable resistor includes a sliding member having an arm in contact with a substantially circular arc-shaped resistor provided on a substrate and a driver plate portion from which the arm extends. The sliding member is rotatable by a driver, the center of the resistor being a supporting point of the sliding member. The driver plate portion of the sliding member is substantially conical and has driver grooves. The arm is connected to the driver plate portion at both sides of a driver groove adjacent an end of the driver groove. Adjustment of a resistance value is performed by rotating the sliding member with a driver tip inserted in the driver grooves.
