Vehicle Pedal Support System

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.
