    摘要: 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.

    摘要: A vibration device includes a first vibration plate having a length direction, the first vibration plate including a first end portion at one end in the length direction and a second end portion at another end in the length direction, a first piezoelectric element provided on the first vibration plate, a first conductive wiring line joined to the first piezoelectric element at a position closer to the first end portion in the length direction than a center of the first vibration plate, a first fixed component connected to the first conductive wiring line, and a case component to which the first fixed component is fixed. The second end portion is a free end, and the first conductive wiring line includes a bent portion.
