PURPOSE:To aim at eliminating the rolling phenomenon, by allowing each air- mat to serve as an independent air spring. CONSTITUTION:Rings as sealing pipes 2-4 are fitted on the outer periphery of a rubber pipe 1. A T-like pipe 5 is closely fitted on the rings 2, 3 extending therebetween while a T-like pipe 6 is closely fitted on the rings 3, 4, extending therebetween. Further, joints 7, 8 for guiding a negative pilot pressure to the rubber hose 1 are fitted into both ends of the rubber hose 1. Further, air is fed into air mats 10a-10g from the T-like hose 7 through vacuum rubber hose valves 6a-6g. With this arrangement the rolling phenomenon may be eliminated.
