To provide a wave-force reduction device capable of preventing a protruded cargo from a hull from being damaged and of improving stabilization of the hull.SOLUTION: The wave-force reduction device provided for a protrusion part 20 protruded on the water comprises a support shaft 55 arranged below the protrusion part 20, a pair of plate-like members 41 and 42 rotatably connected to the support shaft 55 so as to cover the protrusion part 20 from below, and support members 31 and 32 to support the plate-like members 41 and 42. In the wave-force reduction device 30, the pair of plate-like members 41 and 42 are movably provided between the standby position where the pair of plate-like members 41 and 42 have a specified opening angle and the retreating position where they have a bigger opening angle than the angle at the standby position, and they have an elastic member 60 exerting energizing force toward the standby position.SELECTED DRAWING: Figure 3
【課題】船体からはみ出した貨物の波による損傷を防ぎ、かつ、船体の安定化を図ることができる波力低減装置を提供することである。【解決手段】水上に突出する突出部20に対して設けられる波力低減装置であって、突出部20の下方に配置される支軸55と、突出部20を下方から覆うように、支軸55に回動可能な状態で連結されている一対の板状部材41,42と、板状部材41,42を支持する支持部材31,32と、を備える。このような波力低減装置30において、一対の板状部材41,42は、一対の板状部材41,42が所定の開き角度になる待機位置と、待機位置よりも開き角度が大きい退避位置と、の間を移動可能に設けられ、待機位置に向けて付勢力を作用する弾性部材60を有する。【選択図】図3
