Abstract
An adjustable torsion damper has a mount which is divided in the longitudinal direction thereof into two submounts made of a material conductive to magnetism. Located between the two submounts is a portion nonconductive to magnetism. The mount is provided at an upper end thereof and a lower end thereof with a first round hole and a second round hole. The first round hole runs between the submounts. A magnetic block is rotatably disposed in the first round hole. A rotary shaft is rotatably disposed in the second round hole. The rotary shaft is made of a material conductive to magnetism. The value of torsional moment of the rotary shaft changes along with the magnetic block in motion.
