Abstract
A treadmill has an endless belt trained about a front roller and a rear roller assembly. The front roller is connected between a left frame member and a right frame member of the treadmill frame. The rear roller is also connected between the left frame member and right frame member. A bracket connects one end of the rear roller to the frame and has an adjustment mechanism operable to adjust to the front roller to reduce wander of the endless belt. Another bracket connects the other end of the rear roller to the frame and has an adjustment mechanism operable to vary belt tension on the rear roller. One bracket includes a spring operable to continuously urge one end of the rear roller away from the base so the belt tension may be adjusted using the adjustment mechanism of the other bracket.
