To provide a life raft comprising a function for stabilizing the centroid during floating.SOLUTION: A life raft 1 comprises: a three-dimensional frame 10; a floating body 20 retained in the three-dimensional frame 10; and a lid body 30 arranged on a top part of the floating body 20. The lid body 30 is hinged on the three-dimensional frame 10, and has a biparting structure capable of being divided and expanded into two expanded lids 31 relative to the top part of the floating body 20. According to expansion of the lid body 30, the two expanded lids 31 are shifted downward to both sides. The life raft 1 reduces a distance between a center of buoyancy and a center of gravity according to the expansion of the lid body 30 to be able to increase the stability during floating and double a loading area.SELECTED DRAWING: Figure 1

    【課題】浮漂時の重心安定化機能を備えた救命筏を提供すること。【解決手段】本発明の救命筏1は、立体フレーム10と、立体フレーム10内に保持した浮体20と、浮体20の上部に配置した蓋体30と、を備え、蓋体30は、立体フレーム10とヒンジ結合し、浮体20の上部に対して2枚の展開蓋31に分離展開可能な観音開き構造であって、蓋体10の展開によって、2枚の展開蓋31が下方両側に移動することを特徴とする。本発明の救命筏1は、蓋体30の展開によって浮心と重心の距離を縮小して浮漂時の安定性を高めるとともに、積載面積を倍増させることができる。【選択図】図1
