A pedal operation amount detection apparatus for an operation pedal apparatus that includes a transmitting member including a pedal arm of an operation pedal that is disposed to be pivotable about a support axis and subjected to a depressing operation, and an output member to which a depressing operation force is transmitted from the transmitting member and to which a reaction force corresponding to the depressing operation force is applied, the pedal operation amount detection apparatus includes a sensor member disposed on a load transmission path of the transmitting member and the reaction force and the pedal operation amount detection apparatus electrically detects deformation of the sensor member. The sensor member is an elongate member that is torsionally and elastically deformable about a torsion center line in a longitudinal direction and is disposed at a position offset from the transmitting member in a direction parallel to the support axis.

Pedal actuation amount detection device

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.

Pedal operation amount detecting device

An operation amount detection apparatus includes a transmission member that transmits a load corresponding to an operation amount between a shaft portion and an operation target member through connecting portions that connect a first support portion supported by the operation target member and a second support portion supported by the shaft portion, and a detection device that detects an operation amount based on an amount of deformation of the connecting portions. A plurality of the connecting portions are provided in parallel between the first support portion and the second support portion, and deflect due to transmission of a load so that the first support portion and the second support are relatively displaced in a direction of a linear motion. The respective connecting portions are mutually opposed in a direction perpendicular to a lengthwise direction of the shaft portion.

Operation amount detection apparatus

An occupant load sensor of a seat for a vehicle includes a strain member, a connecting member, first and second strain gauge plates, an upper bracket, an amplifier substrate, and an FPC substrate. The strain gauge plates are attached to a surface of the strain member and respectively arranged between a central portion and both end portions of the strain member. Each strain gauge plate includes two strain detecting elements forming a half bridge circuit of a Wheatstone bridge circuit. The FPC substrate is connected to the amplifier substrate and to the strain gauge plates between the both end portions and the central portion of the strain member. Further, the FPC substrate includes a plurality of wiring patterns. The Wheatstone bridge circuit is formed with the plurality of wiring patterns and the half bridge circuit formed at each strain gauge plates.
