Automobile accelerator and brake pedal device

An automobile accelerator and brake pedal device, which is a brake pedal device comprising a vertically operable brake pedal having an auxiliary pad connected thereto, a transversely operable accelerator pad disposed in the auxiliary pad, and acceleration mechanism driven by the accelerator pad, wherein the accelerator pad is in the form of a plate-like member and chevroned with the intermediate portion bulging outward, the acceleration mechanism being operated by the slope surface of the chevron. Even if the brake pedal ( 1 ) is stepped on with the accelerator in its active position, this stepping-on action necessarily causes the accelerator pad ( 9 ) to move forward together with the auxiliary pad ( 3 ), thereby immediately bringing the accelerator lever ( 10 ) back to its original inactive position without any time delay involved as when a different pedal is stepped on, putting off the accelerator, and enabling the brake function to act normally.
