Abstract
A resistance control device for a training appliance includes a resist wheel fixed on the training appliance, and a magnet base adjustable in the distance between the resist wheel and having a plurality of magnets. A right end of the magnet base is pivotally connected to a fix base fixed with the training appliance, and a left end remaining free to move up and down and having a lateral rod. Further, an eccentric block is located at one side of the lateral rod, having a center shaft hole for fixing a shaft rotated by a drive source and a long curved slot for the lateral rod to fit in and move along. The distance between every point of the slot and the center shaft hole is decided by a calculation formula F=Ca.times.S all different. When the eccentric block is moved by the drive source, its moved distance causes the lateral rod also move for the related distance in the slot to rise or lower, altering the distance between the magnet base and the resist wheel so as to control resistance of the resist wheel against the magnet base. So this device is handy, saving time and labor, and adjusting resistance is precise.
