Abstract
A resistance adjustment device of an exercise apparatus include a metal disc that can be driven by movement of a user, a bracket that can be controlled by the user and at least one magnet disposed on the bracket. The magnet can be movable along an adjustment path to approach or move away from a rotation axis of the metal disc so as to increase or decrease a projection area of the magnet on the metal disc for adjusting rotational resistance of the metal disc. The magnet has an irregular quadrilateral cross section gradually widening from a front side closer to the rotation axis to a rear side farther away from the rotation axis, so that during the period of the magnet moving along the adjustment path to approach the rotation axis at a constant speed, the increase rate of the projection area will be gradually accelerated.
