Pedal actuation detector

A pedal operation amount detection apparatus comprising:

• a transmitting member that is provided so as to be pivotable about a support axis, and that transmits a pedal operating force;
• a pivot lever provided on the transmitting member so as to be pivotable about a pivot axis that is parallel to the support axis;
• an output member to which the pedal operating force is transmitted from the transmitting member via the pivot lever, and which applies a reaction force corresponding to the pedal operating force, to the pivot lever;
• and
• a deformable body that is interposed between the transmitting member and the pivot lever, and that deforms based on the reaction force,
• the pedal operation amount detection apparatus electrically detecting a pedal operation amount based on a deformation of the deformable body, and
• the deformable body being fixed to the transmitting member,
• the pedal operation amount detection apparatus further comprising
• a sensor rod fixedly fitted to the deformable body so as to extend upright relative to the deformable body,
• an elastic member provided across the sensor rod and the pivot lever so as to be connected to each other, so that the reaction force is transmitted from the pivot lever to the sensor rod via the elastic member, and
• the sensor rod being passed, with a play, through the pivot lever so that the play allows the pivot lever to pivot.
