PROBLEM TO BE SOLVED: To provide a braking device which detects leg-power applied to a brake pedal, even if the output precision of a linear displacement detector or negative pressure type brake booster deteriorates owing to long-time use. SOLUTION: A pressing portion 12 whose one end is stuck to approximately the center of the backside of a brake pedal 11, a sensor board 13 stuck at the approximate center of its surface to the other end of the pressing portion 12 and provided with a first strain resistance element 18, a second strain resistance element 19, a third strain resistance element 20, a fourth strain resistance element 21, at least two supporting portions 22 whose each one end is stuck to the backside of this sensor board 13, and a brake arm 23 stuck to the other ends of these supporting portions 22, are provided. Leg-power applied to the brake pedal 11 is detected through the pressing portions 12 by the elements 18, 19, 20, 21. |
