PROBLEM TO BE SOLVED: To provide a fender superior in life cycle cost while having superior berthing energy absorbing performance equal to or more than that of rubber in berthing. SOLUTION: This fender is constituted by positioning at least two elastic bodies 1a and 1b formed in circular arc shapes so that respective chord sides become common, and fixing both ends of the elastic bodies by a fixing metal fitting 10. The elastic bodies 1a and 1b can prevent the deterioration of a material by using FRP strong against salt damage. FRP center pillars 2a and 2b having band plate-like or hollow-shaped dislocation preventive structures are slidingly arranged between a plate spring and a plate spring. This member absorbs berthing energy by the expansion of the plate spring in normal berthing, and absorbs the berthing energy by breaking the center pillar or a center pillar joint in berthing in an emergency.
