<p>PROBLEM TO BE SOLVED: To provide a pneumatic fender capable of preventing a flexible hollow body from being damaged and extending a usable life of an energy absorption body.SOLUTION: In a pneumatic fender, a rigid casing 7 with an inner space 7a is protruded on a surface positioned inside a flexible hollow body 4 of either a mounting plate 2 or a front buffer plate 3. Also, orifice sections 10 and a safety valve 8 are installed on the casing 7. The orifice sections 10 communicate the inner space 4a of the flexible hollow body 4 outside the casing 7 with the inner space 7a of the casing 7. When internal pressure P inside the flexible hollow body 4 reaches predetermined pressure P1, the safety valve 8 opens and communicates the inner space 4a of the flexible hollow body 4 outside the casing 7 with the inner space 7a of the casing 7.</p> |
