Patent ID: 8172026

Claim:
A vehicle pedal support system, comprising: body-side components that are separated from each other in a longitudinal direction of the vehicle, and are displaced relative to each other so that a mutual distance between the body-side components in the longitudinal direction of the vehicle is decreased when an external force equal to or greater than a first predetermined value acts on a vehicle front section; a vehicle pedal that has at its lower end portion a depression surface to which a depression force of a driver is applied; a pedal bracket mechanism that is disposed between the body-side components and pivotably supports the vehicle pedal about a pivot; hydraulic pressure conversion section for converting the depression force applied to the depression surface of the vehicle pedal into hydraulic pressure while being swingably supported on the pedal bracket mechanism; and a link mechanism that connects the hydraulic pressure conversion section to an upper-end side of the vehicle pedal in a relatively rotatable manner, and transmits the depression force to the hydraulic pressure conversion section, wherein: a vehicle rear section side of the pedal bracket mechanism includes a deformation portion that serves as a point where the vehicle rear section side of the pedal bracket mechanism starts to undergo bending deformation toward a vehicle rear lower side at the time of the relative displacement between the body-side components, and a non-deformation portion that is located on a vehicle upper side with respect to the deformation portion and comes into contact with the link mechanism at the time of the relative displacement between the body-side components; and the link mechanism is pressed toward the vehicle front section at the time of the relative displacement between the body-side components, thereby causing the depression surface of the vehicle pedal to pivot toward the vehicle front section, the vehicle pedal support system further comprising: a separating mechanism that serves as a point where the vehicle rear section side of the pedal bracket mechanism and the vehicle front section side of the pedal bracket mechanism start to separate from each other in a portion of the pedal bracket mechanism extending on the vehicle lower side with respect to the deformation portion after the vehicle rear section side of the pedal bracket mechanism undergoes bending deformation at the deformation portion at the time of the relative displacement between the body-side components.
