A folding mechanism of a treadmill having a slide pusher (23) at the bottom of a platform frame (10) thereof. By use of a pneumatic cylinder (24), the platform frame (10) may push the rear support in an opposing direction to keep a ground-touching slide action when the platform frame (10) is moved upward and downward. In this way, an effective, strong, and auxiliary support force is created until the platform frame (10) is moved in a vertical storage position or in a horizontal operation position.
