SUSPENSION DEVICE

When a vehicle's driving situation is a rolling state, a compressor is used to transfer compressed air between left and right air suspensions of front wheels, and a compressor is used to transfer compressed air between left and right air suspensions of rear wheels. The air suspensions of the left and right front wheels and the air suspensions of the left and rear wheels thus independently generate counter rolls. This makes it possible to concurrently perform vehicle height adjustment of the air suspensions of the left and right front wheels and vehicle height adjustment of the air suspensions of the left and right rear wheels, which improves responsiveness in counter roll control.
