PROBLEM TO BE SOLVED: To provide a gear structure with angle detection function, which does not need to increase size of whole device, even when an angle detection function is added, and does not need to install an additional angle sensor, therefore saves cost required for installing the angle sensor.SOLUTION: A gear structure 10 comprises a potentiometer function comprising a resistor formation gear 1 and a potential detection gear 2 which occludes with the resistor formation gear 1 and serves as a movable electrode. The resistor formation gear 1 comprises an outer peripheral part resistor 6 contacting the potential detection gear 2, and the outer peripheral part resistor 6 is formed to have an end by interposition of an insulator body part 8. One end part of the outer peripheral part resistor 6 is electrically connected to a surface shaft 3 via a surface electric resistor 5, and the other end part is electrically connected to a rear surface shaft 4 via a rear surface electric resistor 7. |
