PURPOSE:To raise the rigidity by a construction wherein reinforcement members are attached to a rubber bellows at the positions symmetric with respect to the air cushion axis line and over the constant angular range. CONSTITUTION:In the air cushion consisting of the rubber bellows 3 fitted between an upper fixing body and a lower fixing body 1 and 2 and filled up with pressurized air, the reinforcement members 6 are imbedded in the bellows 3 at the positions (a) and (b) symmetric with respect to the air cushion axis line and over the range of a constant angle alpha. According to this construction, the ridigity to the displacement in the front and rear direction of vehicle becomes low and soft feeling for cushionability is obtained. On the other hand, the rigidity to the displacement in the right and left direction of vehicle results high, because the rigidity in the direction at right angle therewith is raised. |
