Abstract
A linear sliding variable resistor comprises a case with a through hole; an operating shaft inserted in the through hole and axially movably locked; an insulated board located in the case and having an electrically conductive pattern on the surface thereof; a sliding contact which slides on the pattern; and a sliding contact retainer which retains the sliding contact and is fixed on the operating shaft. The sliding contact retainer is provided with a pair of snap legs and a retaining portion having a U-sectional recess; and the operating shaft is held by the recess of the retaining portion and the snap legs.
