ABSTRACT:
A rotary variable resistor including a rotator having at an upper part a disk-shaped flange provided with a rectangular first adjustment hole penetrating a circumferential portion thereof and at a lower part a cylindrical shaft, and an adjustment plate having a slider at a lower surface thereof and a second adjustment hole with a narrower width than that of the first adjustment hole on an annular flat plate portion. The rotator is integrated into the adjustment plate by fitting the adjustment plate into the shaft of the rotator with adjusting the position of the first adjustment hole with the second adjustment hole. Thus, a rotary variable resistor is configured. After a product is completed, by applying a force from the side of the first adjustment hole to a side wall in the direction of rotation of the second adjustment hole, the adjustment plate can be moved so as to adjust the output voltage ratio.
