PROBLEM TO BE SOLVED: To provide a lifeboat which reduces the possibility of damage of a hull portion forming an accommodation space even if a collision occurs at a portion in which a hatch is formed.SOLUTION: A lifeboat 100 includes: a hull part 110 including an internal space N including an accommodation space S for accommodating occupants; an impact absorption body 120 which is provided at an outer periphery of the hull part 110 and absorbs an impact from the outside to the hull part 110; a hatch 140a formed in the hull part 110 and through which the occupants get into/out from the internal space N; and a cushioning part (a partition wall 200) forming a cushioning space K at a portion of the internal space N which is located between the accommodation space S and the hatch 140a.SELECTED DRAWING: Figure 4
【課題】出入口が形成される箇所が衝突した場合であっても、収容空間を形成する船体部分の破損のおそれを低減する救命艇を提供する。【解決手段】救命艇100は、乗員が収容される収容空間Sを含む内部空間Nが形成された船体部110と、船体部110の外周に設けられ、外部から船体部110への衝撃を吸収する衝撃吸収体120と、船体部110に形成され、乗員が乗降する出入口140aと、内部空間Nにおける収容空間Sと出入口140aとの間に緩衝空間Kを形成する緩衝部(仕切壁200)とを備える。【選択図】図4
