PROBLEM TO BE SOLVED: To provide a height adjustment device for a railway vehicle, which can reduce air consumption.SOLUTION: A height adjustment device 100 for a railway vehicle, which adjusts the height of a vehicle body 1 with respect to a carriage 2, includes an operation piston 20 (operation body) that is displaced depending on relative displacement of the vehicle body 1 with respect to the carriage 2, a valve rod 30 that is axially moved by displacement of the operation body to switch between the supply and discharge of compressed air to and from an air spring 3, and a damper 60 that imparts resistance to the axial movement of the valve rod 30.

    【課題】空気消費量を低減可能な鉄道車両の高さ調整装置を提供すること。【解決手段】台車2に対する車体1の高さを調整する鉄道車両の高さ調整装置100であって、台車2に対する車体1の相対変位に応じて変位する作動ピストン20(作動体)と、作動体の変位によって軸方向に移動して空気ばね3に対する圧縮空気の供給と排出を切換えるバルブロッド30と、バルブロッド30の軸方向への移動に抵抗を与えるダンパ60と、を備える。【選択図】図2
