Abstract: A vertical pneumatic fender includes a bob connected to a lower hemispherical portion, an internal space containing a predetermined amount of ballast water, a body portion constituted by reinforcing layers layered between an inner rubber layer and an outer rubber layer, cords of adjacently layered upper and lower reinforcing layers disposed intersecting each other at a predetermined cord angle with respect to a cylinder axial direction, and intermediate rubber layers interposed between the reinforcing layers, where the cord angle in a neutral state is set to at least 15° and no more than 45°.
