PURPOSE:To obtain excellent buffer characteristics of low reaction by a method in which a fender body with a hollow chamber is formed of an elastic materials, e.g., rubber, etc., and a plastic material is housed partly in the hollow chamber. CONSTITUTION:Chambers 4 and 5 are provided on the upside and downside of a fender body 1 formed on an elastic material, e.g., rubber, etc., and connected with a communication path 6. A plastic material 3 is packed into the lower chamber 5. When the fender is pressed by a ship, the fender body 1 is pushed to cause an elastic deformation, and thereby the hollow chamber 2 is deformed and the plastic material 3 is pushed up to the upper chamber 4 through the path 6. The elastic deformation of the fender body 1 can thus be suppressed and delayed, whereby permitting the shore contact energy of a ship to be absorbed exactly and also the abrupt increase of reaction to be suppressed. |
