The present invention relates to a rope type folding mechanism for an exercise treadmill. Each end of the U-shaped handrail is provided with a rope wheel whose shaft is pivotably mounted on the extension part at the top of each of the supporting arms. Thereafter, a strong rope is fixed at one side of the rope wheel and pulled downward to the bottom of the frame. When the U-shaped handrail is raised and turned around the shaft, the rope wheel is also rotated to pull the strong rope upward. Thereafter, the frame is raised up to the top by means that the rear roller is turned around the first pivot.
