ABSTRACT:
A rotation angle detecting device includes a housing which is constituted by a combination of a case and a cover; a resistance board; a code wheel; a slider rotating plate; a slider; a circuit board; signal detecting elements; and a gear which transmits the rotation of the code wheel at a predetermined speed reduction ratio to the slider rotating plate, which are enclosed in the housing. Circular pin insertion holes are formed in positions where the code wheel, the case, and the cover face each other, respectively. A pin insertion hole having a circular-arc shape is formed in the slider rotating plate.
