Abstract
A variable resistor whose operating shaft may be click set or stopped to a preselected angular position when a projection of a click spring, which is mounted together with a wiper arm on a wiper arm mounting member, drops into a click slot of a click disk fitted into a cover or a casing generally in the form of a cup. The click disk is rotatably fitted into the cover or the casing in such a way that a torque required for rotating the click disk relative to the cover or the casing is higher than a first torque required for releasing the projection of the click spring out of the click slot of the click disk when the operating shaft is in a first position, but is lower than a torque required for releasing the projection of the click spring out of the click slot of the click disk when the operating shaft is axially shifted from said first position to a second position.
