Abstract
A pneumatic fender having a body portion is configured by laminating a plurality of reinforcing layers between the inner layer rubber and the outer layer rubber. Cords of reinforcing layers are laminated adjacent to each other. The cords intersect and are arranged at a predetermined cord angle with respect to the body axial direction. An intermediate rubber layer is interposed between each of the reinforcing layers. In an uninflated, neutral state, the thicknesses of the intermediate rubber layers are 1 mm to 5 mm, and the cord angle is set from 15° to 45°, so when the interior of the fender is filled with air to the prescribed internal pressure, the cord angle increases to a static angle while the intermediate rubber layers deform in shear, and the body portion increases in diameter and inflates.
