PROBLEM TO BE SOLVED: To carry out grounding load distribution control without requiring large energy, in a vehicle suspension device. SOLUTION: The vehicle suspension device is provided with suspension cylinders 30, 32, 34, 36; first and second controlling cylinders 38, 40; a first lever 42; and a right and left grounding load distribution controlling portion 18 including a first rotation fulcrum moving device 44. When load movement in a fore-and-aft direction occurs in a vehicle, a rotation fulcrum of the first lever 42 is moved to control the load distribution among a left front wheel 10 and a right front wheel 12, and a left rear wheel 14 and a right rear wheel 16. The vehicle suspension device is further provided with the suspension cylinders 30, 32, 34, 36; third and fourth controlling cylinders 150, 152; a second lever 154; and a fore and aft grounding load controlling portion including a second rotation fulcrum moving device 156. When load movement in a lateral direction occurs in the vehicle, a rotation fulcrum of the second lever 154 is moved to control the load distribution among the left front wheel 10 and the left rear wheel 14, and the right front wheel 12 and the right rear wheel 16. The load moving amount occurred in the vehicle is suitably distributed. Therefore, the grounding load of the wheels is controlled to be required amount. COPYRIGHT: (C)2005,JPO&NCIPI
