Pedal support structure for a vehicle

A pedal support structure of a vehicle comprising:

• a pedal support fixed on a vehicle body and supporting a rotation-center shaft of a vehicle pedal;
• a swing link which is supported by a link support in a manner swingable about a swing-center shaft, one end portion of said swing link being connected to operating-force transmission means which transmits a treading force applied to a pad of the vehicle pedal to treading-force boosting means;
• a connecting link which connects the other end portion of said swing link and one end portion of said vehicle pedal opposite to the pad in a relatively rotatable manner, said connecting link transmitting a rotational force of said vehicle pedal, generated about said rotation-center shaft toward the front of the vehicle, to said operating-force transmission means via said swing link, and a connecting pin of said connecting link for connection with the end portion of said vehicle pedal opposite to the pad being offset substantially toward the front of the vehicle or toward the top of the vehicle from a line connecting said rotation-center shaft of said vehicle pedal and said swing-center shaft of said swing link;
• said pedal support and said link support forming a displacement control means which operates, when an external force greater than a predetermined value acts on the front portion of the vehicle, so as to increase the distance between said rotation-center shaft and said swing-center shaft and to shift said connecting pin toward the line, thereby displacing the pad of said vehicle pedal;
• and
• releasing means for releasing the connection, established by said connecting link, between the other end portion of said swing link and the end portion of said vehicle pedal opposite to the pad when the distance between said rotation-center shaft and said swing-center shaft increases, wherein
• said pedal support supporting said rotation-center shaft of said vehicle pedal and said link support supporting said swing-center shaft of said swing link and disposed above said pedal support, so that said link support is moved away from said pedal support when an external force greater than a predetermined value acts on the front portion of the vehicle.
