The present invention relates to an improved belt guiding device for treadmill including a rubber roller jacket on both rollers and the rubber rollers jackets are of proper thickness and the length is slightly less than the length of the rollers. So two ends of the rollers are exposed and is equal in length, also, the length of belt strip is narrower than the lengths of rollers and wider than the length of roller jacket. Therefore, after the belt strip is installed and tightly wrapped on the two rollers, the two roller jackets will generate the bent parts of equal length on the belt strip and these bent parts are able to accurately and effectively guide the belt strip along the rollers during the rotation of the belt strip.
