PROBLEM TO BE SOLVED: To facilitate the installation of torsion bars for cab tilting and keep the tilting effort uniform by increasing their straightness or forming different tooth numbers of serration at their opposite ends and adopting such a greatest common measure relationship between the tooth numbers as ensures straightness within a tolerance range. SOLUTION: The torsion bar structure for vehicle cab tilting comprises a torsion bar 16 having a tooth number of serration 20 at one end and a different tooth number of serration 22 at the other end, a hinge bracket 24 having arm serration 25 and coupled to the one end of the torsion bar 16, and a torsion bar arm 26 having arm serration 27 and coupled to the other end of the torsion bar 16. |
