Abstract

See full text

An operation body is oscillatably supported by a fulcrum member. One side of the operation body is in contact with a projection of an actuator of a pressing force sensor, and a preload is applied to another side of the operation body by a compression coil spring as a preloading elastic member. By the preload, a detection output of the pressing force sensor is set at a neutral point. An operating force by which the one side of the operation body is pressed and an operating force by which the other side of the operation body is pressed can be distinctly detected with the single pressing force sensor.
