Abstract:
A rotary encoder includes a shaft and an encoder mechanism that holds the shaft in a rotatably inserted state and detects a rotation direction and a rotation angle of the shaft. The encoder mechanism includes a substrate that rotatably holds the shaft, an insulator portion and a resistor portion provided on one surface of the substrate and alternately provided in the rotation direction of the shaft, a rotor attached to the shaft so as to be integrally rotatable with the shaft, and a slider that is attached to the rotor and alternately slidably contacts the insulator portion and the resistor portion by rotation of the shaft. The insulator portion includes a base material made of a resin, spherical silica, and a fluororesin filler.
