Patent ID: 8333130

Claim:
An operating pedal device for vehicle, comprising: an operating pedal mounted on a pedal support fixedly secured to a vehicle to be pivotable about an axis of a support shaft and operative to be depressed by a driver; a reactive member connected to the operating pedal via at least one connecting section which allows relative pivotal movement between the operating pedal and the reactive member about a connecting pin to which an output is transferred at a rate depending on an operational force of the operating pedal and which is applied with a reaction force corresponding to the output; a pedal side member connected relatively pivotably via the connecting pin at a connecting position with the connecting pin and forming a sensor mounting hole therein, and a load sensor electrically detecting the operational force, which is fixedly attached in the sensor mounting hole and through which the connecting pin is passed to be disposed concentrically with an axis of the sensor mounting hole; and the load sensor including a detecting member formed in a cylindrical shape; an annular first mounting member provided on an outer circumferential periphery of the detecting member, unitarily fixing one axial end portion of the detecting member, and being unitarily mounted in the sensor mounting hole; a second mounting member provided on an inner circumferential periphery of the detecting member, unitarily fixing other axial end portion of the detecting member, and having an insertion bore through which the connecting pin is inserted; a strain detecting element fixed to the detecting member; a first annular space provided successively on the inner circumferential periphery of the first mounting member at one radial side of the detecting member and a second annular space provided successively on the outer continuous circumferential periphery of the second mounting member at other radial side of the detecting member such that the first annular space and the second annular space allow a relative shifting between the first mounting member and the second mounting member in a radial direction of the detecting member; and the first mounting member and second mounting member being displaceable relative to each other depending on the operational force, to allow the strain detecting element to detect a shear strain occurring in the detecting member.
