Abstract
A torsion bar device includes a torsion bar having a torsional portion, an upper connecting portion associated with an input shaft, and a lower connecting portion associated with an output shaft; a first cylinder for encompassing the torsional portion, one end of the first cylinder being connected to one of the upper and lower connecting portions, and the other end of the first cylinder extending in the longitudinal direction of the torsion bar to the other connecting portion of the torsion bar; a second cylinder for encompassing and being connected to the other one of the upper and lower connecting portions of the torsion bar; a first supporting member for supporting the torsion bar at the other end of the first cylinder in a circumferential direction of the torsion bar; a second supporting member for supporting the torsion bar in the circumferential direction at a portion of the second cylinder where the second supporting member is aligned with the first supporting member; and an elastic member for elastically restoring the alignment of the first and second supporting members by applying a force in a direction opposite to a torsionally stressed circumferential direction of the torsion bar when a steering wheel is turned so as to regain the original neutral position of the steering wheel.
