Abstract: The present invention simplifies the configuration of a rotary encoder. In the present invention, a plate spring 3, which includes a plurality of arm sections 3BX to 3FX where curving projection sections 3BZ to 3FZ are formed and whose tips are movable contacts 3BX to 3FX, is attached to a base 2 including a plurality of fixed contacts 6 to 10. In addition, a gear 4, whose one surface's concentric positions are equipped with a plurality of curving-line-shaped projection sections 4C to 4G, is attached so that it can rotate. When the gear 4 rotates, the curving-line-shaped projection sections 4C to 4G push the curving projection sections 3BZ to 3FZ and the movable contacts 3BX to 3FX of the arm sections 3B to 3F touch the fixed contacts 6 to 10. Accordingly, since there is no component between the gear 4 and the plate spring 3 to push down the arm sections 3B to 3F, the configuration of the rotary encoder 1 can be simplified.
