ABSTRACT:
In a motor-driven slide type variable resistor, the tensioning of a toothed loop belt joined to an operating lever is adjusted with a pin adjusted to change the distance between a toothed pulley and a follower pulley in order to adjust a traveling speed of the operating lever. The variable resistor has little variations of the traveling speed of the operating lever and is accurate
