Patent attributes
A pedal operation amount detection apparatus comprises: a transmitting member; a pivot lever provided on the transmitting member; and a deformable body, the pedal operation amount detection apparatus electrically detecting a pedal operation amount based on a deformation of the deformable body, the deformable body is fixed to the transmitting member, a sensor rod is fixedly fitted to the deformable body so as to extend upright relative to the deformable body, an elastic member is provided across the sensor rod and the pivot lever so as to be connected to each other, so that the pedal operating force or a reaction force corresponding to the pedal operating force is transmitted from the pivot lever to the sensor rod via the elastic member, and the sensor rod is passed, with a play, through the pivot lever so that the play allows the pivot lever to pivot.
