To provide a horizontal vibration suppression device capable of actively suppressing horizontal vibrations acting on a seat.SOLUTION: A horizontal vibration suppression device suppresses horizontal vibrations acting on a seat 20 in a vehicle in which movable parts 21, 22, 23 moving integrally with the seat 20 are configured to be slidable in a horizontal direction seen from an occupant with respect to stationary parts 91, 92, 93 whose horizontal directions are fixed to a vehicle body 90. A fluid pressure actuator 30 reciprocally displaces a relative position between the stationary parts and the movable parts by movement of an output part 33 corresponding to the magnitude of fluid pressure between a first fluid chamber 31 and a second fluid chamber 32. A two-way switching valve 50 is provided between an external fluid pressure supply source 60 and the fluid pressure actuator 30, and switches a channel so as to supply fluid to one of the first fluid chamber 31 and the second fluid chamber 32 and discharge the fluid from the other. A control part 80 acquires information on horizontal vibrations acting on the seat 20, and operates the two-way switching valve 50 so as to suppress the horizontal vibrations and control the operation of the fluid pressure actuator 30.SELECTED DRAWING: Figure 1

    【課題】座席に作用する横振動をアクティブに抑制可能な横振動抑制装置を提供する。【解決手段】横振動抑制装置は、座席20と一体に動く可動部21、22、23が、車体90に左右方向が固定された固定部91、92、93に対し乗員から見て左右方向にスライド可能に構成された車両において、座席20に作用する横振動を抑制する。流体圧アクチュエータ30は、第1流体室31と第2流体室32との流体圧の大小に応じた出力部33の動作により、固定部と可動部との相対位置を往復変位させる。二方向切替弁50は、外部の流体圧供給源60と流体圧アクチュエータ30との間に設けられ、第1流体室31又は第2流体室32の一方に流体を供給し、他方から流体を排出するように流路を切り替える。制御部80は、座席20に作用する横振動に関する情報を取得し、横振動を抑制するように二方向切替弁50を操作して流体圧アクチュエータ30の動作を制御する。【選択図】図1
