A motor vehicle having a cab which is pivoted frontally to the chassis includes a torsion bar, the reaction moment of which acts through a crank arm and a cam-follower roller on a cam fixed to the base of the cab. The cab is safely and conveniently tiltable since the shape of the cam surface is such that the cab is in neutral equilibrium in any position between its lowered and raised positions. |
