Abstract

The present invention relates to a treadmill having a base frame with a handrail. The base frame is provided with two rollers at both ends thereof. A support plate is interposed between both rollers. And a walking belt is disposed around the rollers and the support plate. The base frame has a plurality of crossbars in the position of the support plate, and the crossbars is provided with at least one buffer piece in the middle thereof which is in contact with the bottom face of the support plate. A support element has a bottom member on the base frame and a top member fixed on the bottom of the support plate, and both members are pivotably connected, thereby positioning the support plate indirectly on the base frame. Accordingly, the injury of the feet is avoided and the service life of the support plate is prolonged.
