Abstract
A treadmill includes a treadmill frame and a lever having front portions pivotally secured to a base, and foldable or rotatable up and down between upward folding position and downward working position. A leg is pivotally secured between rear portions of the treadmill frame and the rear portion of the lever, to form a quadrilateral structure together with the treadmill frame and the lever. A driving device is coupled between the leg and the treadmill frame, to force the leg to rotate relative to the treadmill frame and the lever, and thus to rotate the treadmill frame and the lever relative to the base between upward folding position and downward working position.
