To provide a railway vehicle vibration suppressing device which improves a ride comfort in a railway vehicle even if a non-return valve fails.SOLUTION: A railway vehicle vibration suppressing device 1 comprises a cylinder body Cy which is arranged between a vehicle body B and a truck T of a railway vehicle and can move telescopically by supplying operational liquid, a pump 12 which, when normally rotated, supplies operational liquid to the cylinder body Cy through a supply path 16, an actuator A with a non-return valve 17 which is installed in cylinder body Cy side from the pump 12 in a supply path 16 and permits only the operational liquid to flow from the pump 12 to the cylinder body Cy, a rotation position sensor 43 to detect a reverse rotation of the pump 12 and a reverse rotation suppressing device C which suppresses the reverse rotation of the pump 12 when the rotation position sensor 43 detects reverse rotation of the pump 12 during stopping of the pump 12.SELECTED DRAWING: Figure 2

    【課題】逆止弁に異常が生じても鉄道車両における乗心地を向上できる鉄道車両用制振装置の提供である。【解決手段】鉄道車両用制振装置1は、鉄道車両の車体Bと台車Tとの間に介装されて作動液体の供給により伸縮可能なシリンダ本体Cyと、正回転すると供給通路16を介して作動液体をシリンダ本体Cyへ供給するポンプ12と、供給通路16の途中であってポンプ12よりもシリンダ本体Cy側に設けられてポンプ12からシリンダ本体Cyへ向かう作動液体の流れをのみを許容する逆止弁17とを備えたアクチュエータAと、ポンプ12の逆回転を検知する回転位置センサ43と、ポンプ12の停止中に回転位置センサ43がポンプ12の逆回転を検知するとポンプ12の逆回転を抑制する逆回転抑制装置Cとを備えている。【選択図】図2
