ABSTRACT:
A motorized treadmill has a right roller bracket and a left roller bracket with a tail roller interconnected thereinbetween. The brackets mate into the left extension and the right extension respectively of the treadmill frame. The treadmill frame is unitarily formed and is "U" shaped. The left and right roller bracket together with the tail roller secure the rear ends of the left and right extensions together and hold them in a spaced apart condition. in addition, belt guides are positioned to guide the lower stretch of the endless belt. The belt guides extend upwardly and inwardly and forwardly at preselected angles to minimize belt wear and belt noise in operation.
