ABSTRACT:
A variable resistor of the type having a substantially curved resistor provided on a substrate has an arm portion of a sliding member contacting therewith, the sliding member being rotatable, with a central portion of the resistor as a supporting point, for adjusting the resistance value by rotating the sliding member with a driver. A driver plate of the sliding member is formed substantially into a cone in shape, in which cone a driver groove portion is provided. The driver tip is guided by the conic portion and inserted into the driver groove portion.
