Claim Text:
1. A pedal operation amount detecting device that is provided in an operating pedal apparatus including a transmitting member having a pedal arm of an operating pedal that is arranged so as to be pivotable about a support axis and that is depressed, and an output member to which a depression force is transmitted from the transmitting member and to which a reaction force corresponding to the depression force is applied, the pedal operation amount detecting device including a sensor member that is arranged on a load transmission path at a position offset from the transmitting member in a direction parallel to the support axis and that is deformed by the depression force and the reaction force, and the pedal operation amount detecting device electrically detecting; a deformation of the sensor member: the sensor member being arranged on the transmitting member via a pair of support pins which are parallel to the support axis, respectively, on which a coupling pin is arranged to penetrate the sensor member and relatively rotatable around an axis parallel to the support pin, such that the depression force is applied to the sensor member from one of the transmitting member and the coupling pin, and the reaction force is applied to the sensor member from the other one, an operation input portion through which the depression force is applied to the sensor member and a reaction force applied portion through which the reaction force is applied to the sensor member being set at positions that overlap with each other in a direction substantially parallel to the support axis, and the sensor member being disposed on one of opposite side faces of the transmitting member, the opposite side faces being opposite to each other in the direction parallel to the support axis.
