<p>Making it possible to easily configure, at low cost, a pedal operation amount detection apparatus that electrically detects a pedal operation amount based on a deformation of a deformable body, while ensuring a prescribed detection accuracy. A sensor rod 46 is fixedly fitted to a deformable body 44 so as to extend upright relative to the deformable body 44 fixed to an operating pedal 16 via a bracket 42, and the sensor rod 46 and a pivot lever 20 are connected to each other via a compression coil spring 48. Therefore, the pedal operation amount detection apparatus is easily configured at low cost. Further, a brake reaction force R is transmitted from the pivot lever 20 to the sensor rod 46 via the compression coil spring 48. This makes it possible to restrict inputs of disturbances such as engine vibrations to ensure a prescribed detection accuracy, in comparison with a case where a pedal operation amount is detected based on the deformation of the pivot lever 20.</p> |
