A quasifixed variable resistor includes a resistor substrate with a resistor mounted thereon, a stopper plate rotatably retained about an axis on the substrate, and a knob having a slider fixed to an end of the stopper plate, the slider, sliding on the resistor. In a flat portion located at a bottom end of a cylindrical section of the stopper plate, a screwdriver engaging section having an adjusting groove is folded and is integrally formed therein. A wing piece branched by the adjusting groove is tapered in a direction toward the flat portion and a tip end of the screwdriver can be engaged with an end portion of the wing piece for adjustment.
