ABSTRACT:
A load sensor includes a load-input unit, an hourglass-shaped coil spring having one end coupled to the load input unit, a load-applying unit disposed at the other end of the hourglass-shaped coil spring, and a load detector for receiving the load from the load-applying unit and detecting the load. The load sensor does not give a user an uncomfortable pedal feeling, similarly to a hydraulic brake.
