Abstract: A pneumatic fender and a mouth piece metal with an open/close valve is biased by a resilient member toward a closing direction of a through hole formed on a dividing wall constituting a receiving chamber. A safety valve is isolated from a cavity of a fender bladder by a receiving chamber, thus allowing the safety valve to be able to be detached and attached while the pneumatic fender is in use. A confirmation test of a valve opening pressure of the safety valve is performed by opening a receiving chamber open/close valve and raising an internal pressure of a cavity of the receiving chamber to a pressure threshold (Pm) via a receiving chamber communication passage. Upon an internal pressure (P) of the cavity being less than the pressure threshold (Pm) and greater than a standard pressure (Pc), the open/close valve opens the through hole, thus allowing the safety valve to function.
