This is a method for measuring the pedal force of an automobile pedal, in which the operating lever is rotated around the pivot point so as to cross the "F stroke x load" curve, and the measuring operation involves pressing down on the end of the operating lever. The labor is reduced because it is only a tedious task of returning the material. Since the operating lever and the pedal arm have the same pivot point, the perpendicularity of the load cell to the footplate of the pedal arm does not change throughout the entire operation, making it possible to obtain an accurate hysteresis curve with only one operation. Therefore, the number of work steps is significantly reduced.
