<p>PROBLEM TO BE SOLVED: To provide a small-sized motor drive type sliding variable resistor of low height, having a short control lever with a toothed belt and a toothed pulley, etc., exposed to the outside, and to reduce assembling man-hours. SOLUTION: A metal case 15 is extended in the longitudinal direction and integrally provided with the mouthing part of a motor 3 and the mounting part of a follower pulley 6. A ring-like toothed belt 7 is stretchingly provided in the metal case 15, and the slidingly moving body 16 which retains an elastic contact part 11, is moved rectilinearly. As a result, the height of the entire body can be made low, and moving parts are not exposed to the outside.</p> |
