Rod or bar that resists twisting (see torque) and has a strong tendency to return to its original position when twisted.

In an automobile, a torsion bar is a long spring-steel element with one end held rigidly to the frame and the other end twisted by a lever connected to the axle. It thus provides a spring action for the vehicle.
