The invention belongs to the field of automobile accessories, and relates to a folding pedal of a cab of a flat-head heavy truck. Two parallelogram pedals are installed on the two sides of the front portion of the bottom of a flat-head heavy truck cab respectively. Two cylindrical air cylinders are installed on a cab bottom plate behind a pedal through two rectangular hinges, the top ends of piston rods of the air cylinders are connected with the center of a vertical plate on the right side of the pedal through a round ball head, and the two sides of the lower right portion of the inner side of a cab door are each provided with a cylindrical contact type reversing valve. A cylindrical air storage tank is installed behind the cab and connected with a contact type reversing valve through an air supply pipeline, and the contact type reversing valve is connected with an air cylinder through an air supply pipeline. When a driver opens the automobile door, a contact rod at the front end of the contact type reversing valve is released, the contact type reversing valve supplies high-pressure gas of the gas storage tank to the air cylinder, a piston rod at the front end of the air cylinder is pushed out to drive the pedal to move downwards to be in a vertical state, and the driver can step on the pedal to get on the automobile smoothly.
