To solve problems of incorrectly stepping an accelerator pedal and a brake pedal, and requiring re-stepping time due to re-stepping operation of the accelerator pedal and the brake pedal by a right foot.

The accelerator pedal 1 and the brake pedal 2 are distributively arranged on the left and right to a steering wheel 5 so that the brake pedal 2 can be instantly stepped by a left foot placed in a quick response position in the vicinity of the brake pedal 2. Thus, a body posture can be put in a normal posture of turning to the front by placing the right foot for stepping the accelerator pedal 1 on the right side, and the left foot for stepping the brake pedal 2 on the left side.
