VEHICLE OPERATION PEDAL DEVICE

摘要

A vehicle operation pedal apparatus comprising an operation pedal supported by a pedal support member so as to be pivotable about one axis, and a return spring having one end portion engaged with a bracket plate member disposed on the operation pedal and the other end portion engaged with a position fixing member, the operation pedal being returned by pivoting in accordance with an urging force of the return spring upon cancellation of a depressing operation of the operation pedal, the vehicle operation pedal apparatus further comprising an engagement hook being formed in the one end portion of the return spring by bending an end portion of a wire rod that constitutes the return spring, and an engagement hole or cutout into which the engagement hook is hooked being formed in the bracket plate member disposed on the operation pedal so as to pass through the bracket plate member, a surface direction of a portion of the bracket plate member, in which the engagement hole or cutout is formed, being set such that a contact point at which the engagement hook contacts one of a pair of edges that are ridgelines between an inner wall surface of the engagement hole or cutout and one surface and the other surface of the bracket plate member is a relative pivot point of the return spring that pivots relative to the operation pedal in accordance with a pivoting operation of the operation pedal in an entire operation angle range of the operation pedal.
