This invention is relating to a buffer structure to be installed in between the framework of jogging machine and the floor surface. The jogging machine is comprised of one framework, one front floor-rod, one hand holder and one rear floor-rod, etc. components. Amid the components, framework has a jogging board installed on its end surface. And one jogging track is enclosed to surface of this jogging board on its up and down end. Thus this installation can enable user to stand on jogging track and start jogging exercise. The key point here is that there is a pulling board transversely pivoted to the top end of two bent chips incorporated to rear floor-rod. And one side of the pulling board has a pivot lug to pivot an adjustment screw rod. Then let this screw rod pass through the holes drilled on the front & rear partition boards and place a buffer pad in between front and rear partition boards. Finally use one screw rod socket and one knob to bolt screw rod together. After the buffer pad is installed, it can effectively absorb the gravity that framework is carrying. It can also lessen the reaction force fed back by floor surface, and further to weaken the vibration phenomena created when framework is stressed.
