PURPOSE: A damage alarm device of a torsion bar is provided to ring alarm by reducing the pressure of the air injected into a hollow part of a torsion bar and falling down first and second terminals in case of damage to the torsion bar. CONSTITUTION: A damage alarm device(1) of a torsion bar comprises a torsion bar. The torsion bar prevents the horizontal inclination of a vehicle. The torsion bar comprises a hollow part(1b), a cylinder(10), a piston(15), and an elastic member(16). The hollow part is formed inside the torsion bar in the longitudinal direction. The cylinder is communicated with a hollow part. The piston is embedded within a cylinder to be slid. The elastic member elastically supports the piston inside the cylinder. A first terminal(25) is arranged inside the cylinder. The first terminal is connected to one among a power supply part(30) and an alarm device(20). The second terminal(35) is arranged on the piston. The second terminal is connected to one among the power supply part and the alarm device. |
