Abstract
A contactless potentiometer includes a shaft and a magnet rotatable together with the shaft and detects a rotational angle of the shaft corresponding to a change in magnetic fields caused by the rotation of the magnet, the magnet being held in a tip end portion of the shaft. The potentiometer includes a cover member attached to a housing at a tip end side of the shaft and arranged to define a closed sensor area between the cover member and the housing, and a circuit board mounted to the cover member at a side of the sensor area in a perpendicular or substantially perpendicular relationship with the shaft. The cover member includes a recess portion arranged on a surface of the cover member facing the circuit board, the recess portion cooperating with the circuit board to define a component-mounting spare space.
