Abstract

A treadmill includes two rollers rotatably secured in a base, an endless belt engaged over the rollers, and a motor disposed in the base and coupled to one of the rollers for driving the endless belt. A shielding device is disposed between the motor and the endless belt for shielding the motor and for preventing the endless belt to carry dust to dirt the motor. The users may carry the dust onto the endless belt, and the dust may then be carried toward the motor, but may be shielded by the shielding device and may be prevented from dirtying the motor.
