PURPOSE: A roll over prevention shock absorber is provided to prevent the roll over by reducing the instantaneous rotating angle by using a tip-up unit restraining the rebound stroke of a piston with the operation due to the hydraulic pressure. CONSTITUTION: A roll over prevention shock absorber comprises a rebound stopper, a tip-up unit(13), and a hydraulic pressure supply unit(30). The rebound stopper is formed on the top of a piston(7). The tip-up unit is formed on the side of the top of the inner surface of a cylinder(3). The tip tip-up unit restrains the lifting operation of the piston with the hydraulic pressure supplied from the outside in the control timing. The tip-up operation is generated in a front wheel by the tip-up unit. The hydraulic pressure supply unit supplies the hydraulic pressure to the tip-up unit according to the control signal of a controller. |
