(54) Device for effecting resistance


(57) A device for effecting resistance is incorporated into an exercise or rehabilitation machine and is formed of an excited magnetic cylinder (10), an excited magnetic coil (20), a rotary cylinder (30), and two support frames (40). As the excited magnetic coil is connected to the alternating current power source in conjunction with a control switch, the exercise or rehabilitation machine is provided with a magnetic resistance of a predetermined magnitude. The excited magnetic cylinder is provided in one side with an annular wavy magnetic interstice for guiding the magnetic line toward the rotary cylinder, thereby resulting in a magnetic resistance causing the fixed excited magnetic cylinder and the rotary cylinder to attract each other. The rotary cylinder is connected to a link device of the exercise or rehabilitation machine, so as to provide the exercise or rehabilitation machine with a resistance.
