Pneumatic fender and manufacturing method therefor

A pneumatic fender which comprises a body comprising a body portion having a cylindrical shape, and a hemispherical portion having a bowl shape connected to both ends of the body portion, in which the body is constituted by a plurality of reinforcing layers layered between an inner layer rubber and an outer layer rubber, each of the reinforcing layers in the body portion is formed of multiple cords aligned to extend in parallel at a predetermined cord angle with respect to a cylinder axial direction, the cords of the reinforcing layers layered adjacently have an intersecting bias structure, and the cord angle in a neutral state where the body is not expanded is set to 25° or more and 45° or less,

• both end portions in the cylinder axial direction of each of the reinforcing layers of the body portion and each of the corresponding reinforcing layers of the hemispherical portion facing each other with a space,
• members facing each other being bonded with a bonding member interposed between the members facing each other, the bonding member disposed in each of the spaces,
• each of the bonding members being formed of multiple cords aligned to extend in parallel,
• the multiple cords of the bonding members extending in an orientation identical to an orientation of the cords of a corresponding bonding target reinforcing layer of the body portion,
• a cord angle of the cords of the bonding members being set to ±10° of the cord angle of the cords of the bonding target reinforcing layer in a neutral state where the body is not expanded, and
• the spaces having a plurality of different sizes, one set of ends of the spaces being set to a plurality of different positions, and an other set of ends of the spaces being set to a plurality of different positions, with respect to a circumferential direction of the hemispherical portion having an arcuate shape in a side view of the body.
