가요성 중공체 및 에너지 흡수체의 손상을 억제하는 것과 함께, 선박의 요동 저감 효과를 향상시킨 공기식 방현재를 제공한다. 일방(一方)의 취부판(2a)의 표면에, 내부 공간(7A)을 가지는 강체의 케이싱(7)을 돌설(突設)하고, 가요성(可撓性) 중공체(中空體)(4)의 내부 공간(4A)과 케이싱(7)의 내부 공간(7A)을 연통시키는 오리피스(orifice)부(10)와 가요성 중공체(4)의 내압(P)이 소정 압력(P1)에 이르렀을 때에 개변(開弁)하여 가요성 중공체(4)의 내부 공간(4A)과 케이싱(7)의 내부 공간(7A)을 연통시키는 안전 밸브(8)를 설치한다. Provided is a pneumatic fender that suppresses damage to a flexible hollow body and an energy-absorbing body and exhibits improved ship sway reduction effects. A pneumatic fender is provided with an orifice (10) that allows for communication between an interior space (4A) of a flexible hollow body (4) and the interior space (7A) of the casing (7), and a safety valve (8) that opens and allows for communication between the internal space (4A) of the flexible hollow body (4) and the internal space (7A) of the casing (7) by opening when the internal pressure (P) of the flexible hollow body (4) reaches a predetermined pressure (P1).
