Abstract
A treadmill includes a base frame, a treadmill belt, a plurality of bearing wheels, a bearing frame, and a limiting frame. The treadmill belt is rotatably installed on the base frame. The bearing wheel is mounted on an inner surface of the treadmill belt. Each bearing wheel is inclined with respect to a horizontal plane, and the bearing frame and the limiting frame are both mounted on the base frame. The bearing frame supports the bearing wheels of the upper section of the treadmill belt. The limiting frame is disposed on one side of the bearing wheel and abuts the bearing wheel. The treadmill has the advantages that the friction between the limiting frame and the bearing wheels can be reduced and can avoid sudden stop or sticking.
