Claims

[Claims for Utility Model Registration] (1) A pair of brackets fixed to the left and right chassis frames of a vehicle, and a bracket installed through these brackets, with one end fixed to one of said brackets and the other end fixed to said bracket. A torsion bar device for cab tilting comprising a torsion bar rotatably supported on the other side of the bracket, and a torsion lever fixed to the other end of the torsion bar for tilting the cab, wherein a serration is formed at one end of the torsion bar. A plurality of screw holes are provided around one through hole of the bracket, and a sleeve has a serration hole that fits into the serration hole and has a plurality of bolt holes around the serration hole. It is fixed to one of the brackets by tightening bolts to the screw holes through the sleeve, and the plurality of bolt holes or screw holes have different phase angles with respect to the center of the sleeve with the teeth constituting the serration hole. A torsion bar device for cab tilt, characterized by being provided with a torsion bar device. (2) A pair of brackets fixed to the left and right chassis frames of the vehicle, and a bracket installed through these brackets so that one end is fixed to one of the brackets and the other end is rotatable to the other bracket. A cab tilt torsion bar device comprising a supported torsion bar and a torsion lever fixed to the other end of the torsion bar for tilting the cab, wherein a serration is formed at one end of the torsion bar, and a serration is formed at one end of the torsion bar, and a serration is formed through one end of the bracket. A plurality of screw holes are provided around the hole, and a sleeve having a serration hole that fits into the serration hole and a plurality of bolt holes around the serration hole is bolted to the screw hole through the bolt hole. The outer peripheral surface of the sleeve is formed into a wheel gear, and a worm gear that meshes with the wheel gear is rotatably supported by the bracket or the chassis frame and rotates the worm gear shaft. A torsion bar device for cab tilt, characterized in that the torsion bar device is configured to adjust the torsion force of the torsion bar by moving the torsion bar.
