Abstract
A magnetically controlled load-adjusting device of a gymnastic apparatus comprises a frame provided with a load wheel having a thin metal piece, and a base frame having one end provided pivotally with a swivel seat. The base frame has another end provided with a decelerating mechanism. The base frame is provided in the middle thereof with an arresting member which is connected at one end thereof with the swivel seat and is capable of being acted on by an elastic element to become attached intimately to the circumferential surface of an eccentric wheel of the decelerating mechanism. The distance between the arresting member and the axial center of the eccentric wheel is changed by the decelerating mechanism, so as to cause the swivel seat to swivel at an appropriate angle. The magnitude of the magnetic flux of the load wheel is therefore altered by the magnets mounted on the swivel seat, thereby bringing about an adjustment of the magnitude of the magnetic damping of the gymnastic apparatus.
