Abstract
A pressure-sensitive conductive rubber for reference is provided inside a housing in such a state that preload is imposed thereon. A pressure-sensitive conductive rubber for detection is also provided inside the housing in such a state that preload is imposed thereon and an external load acts thereon. A load detecting circuit applies voltage to the pressure-sensitive conductive rubbers to determine the external load based on a difference between a detected value corresponding to electric current flowing through the pressure-sensitive conductive rubber for reference and a detected value corresponding to electric current flowing through the pressure-sensitive conductive rubber for detection.
