ABSTRACT:
A plurality of hollow torsion-bar members are arranged coaxially, and ERF (Electro Rheological Fluid), which increases its viscosity and holds the hollow torsion-bar members together as a unit when a certain voltage is applied, is loaded into the clearances between the hollow torsion-bar members. Electric terminals are installed at one end of each hollow torsion-bar member so that voltage is applied to the hollow torsion-bar members.
