PROBLEM TO BE SOLVED: To stabilize the posture of a collision energy absorption device during deformation while absorbing desired collision energy and reducing a load peak value at an initial stage of collision.SOLUTION: A collision energy absorption device of a railway vehicle comprises an outer plate constituting an outer cylinder having an axis line extending in a vehicle longitudinal direction, and at least one partition plate extending in the vehicle longitudinal direction in an interior space surrounded by the outer plate, fixed to the outer plate, and partitioning the interior space. An outer shape of the outer cylinder has a symmetrical shape with a virtual horizontal plane including the axis line as a reference. The at least one partition plate has a missing part in the interior space.SELECTED DRAWING: Figure 2
【課題】所望の衝突エネルギーを吸収して且つ衝突初期の荷重ピーク値を低減させながらも、衝突エネルギー吸収装置の変形時の姿勢を安定させる。【解決手段】鉄道車両の衝突エネルギー吸収装置は、車両長手方向に延びる軸線を有する外筒を構成する外板と、前記外板に囲まれた内部空間で前記車両長手方向に延び、前記外板に固定されて前記内部空間を仕切る少なくとも1つの仕切板と、を備え、前記外筒の外形は、前記軸線を含む仮想水平面を基準として対称な形状を有し、前記少なくとも1つの仕切板は、前記内部空間において欠落部を有する。【選択図】図2
