PROBLEM TO BE SOLVED: To provide a damper and a damping device for a railway vehicle which can damp vibration of a vehicle body by making damping force variable and damp shaking of the vehicle body, and further can reduce costs by reducing the number of electric drive valves per carriage.SOLUTION: A damping device S for a railway vehicle comprises a pair of dampers DL and DR which are interposed between a vehicle body B and a carriage W of a railway vehicle V. The dampers DL and DR are configured to exert damping force only by either being extended or being contracted, and can make the damping force variable. One damper DL exerts the damping force when the vehicle body B moves in a left direction with respect to the carriage W, and the other damper DR exerts the damping force when the vehicle body B moves in a right direction with respect to the carriage W.SELECTED DRAWING: Figure 2

    【課題】 減衰力を可変にして車体の振動を抑制するとともに、車体の加振を抑制できるようにしたとしても、台車一台当たりの電気的駆動弁の数を減らしてコストを低減できるダンパ及び鉄道車両用制振装置を提供する。【解決手段】 鉄道車両用制振装置Sは、鉄道車両Vの車体Bと台車Wとの間に介装される一対のダンパDL,DRを備え、これらのダンパDL,DRは、ともに、伸長或いは収縮の一方でのみ減衰力を発揮するとともに、上記減衰力が可変であり、一方のダンパDLは、台車Wに対して前記車体Bが左方向へ移動するときに減衰力を発揮し、他方のダンパDRは、台車Wに対して車体Bが右方向へ移動するときに減衰力を発揮する。【選択図】 図2
