Provided is a vertical pneumatic fender that is capable of responding to sudden increases in berthing impact energy. A bob (11) is connected to a lower hemispherical portion (3), an internal space contains a predetermined amount of ballast water (W), a body portion (2) is constituted by a plurality of reinforcing layers (5) layered between an inner rubber layer (4) and an outer rubber layer (7), cords (6a, 6b) of adjacently layered upper and lower reinforcing layers (5) are disposed intersecting each other at a predetermined cord angle (A) with respect to a cylinder axial direction, intermediate rubber layers (8) are interposed between the reinforcing layers (5), and the cord angle (A) in a neutral state is set to at least 15° and no more than 45°, with the result that, when additional air (a) is injected into the internal space of a fender (1) via an injection tube (12a) of an air injection device (12), the cord angle (A) increases to roughly an angle of repose as the intermediate rubber layers (8) engage in shear deformation, causing the body portion (2) to expand and inflate, rapidly increasing the energy-absorbing capability of the fender (1).
