PROBLEM TO BE SOLVED: To provide a semiactive damper capable of reducing the size and the cost, and capable of improving riding comfort in a vehicle.MEANS FOR SOLVING THE PROBLEM: A semiactive damper D of this invention includes a cylinder 1, a rod 2 movably inserted into the cylinder 1, a piston 3 slidably inserted into the cylinder 1 and partitioning the inside of the cylinder 1 into a rod side chamber 4 and a piston side chamber 5, a tank 6, a suction passage 7 allowing only the flow of working fluid flowing from the tank 6 to the piston side chamber 5, a damping passage 8 communicating the rod side chamber 4 with the tank 6 or communicating the rod side chamber 4 with the piston side chamber 5, a variable damping valve 9 provided in the damping passage 8, and a detecting section 10 for detecting an extension and contraction direction by a pressure in the piston side chamber 5.SELECTED DRAWING: Figure 1

    【課題】小型化およびコスト低減を可能とするとともに車両における乗心地を向上できるセミアクティブダンパの提供である。【課題を解決するための手段】本発明のセミアクティブダンパDは、シリンダ1と、シリンダ1内に移動自在に挿入されるロッド2と、シリンダ1内に摺動自在に挿入されてシリンダ1内をロッド側室4とピストン側室5とに区画するピストン3と、タンク6と、タンク6からピストン側室5へ向かう作動流体の流れのみを許容する吸込通路7と、ロッド側室4とタンク6とを連通するか或いはロッド側室4とピストン側室5とを連通する減衰通路8と、減衰通路8に設けられた可変減衰弁9と、ピストン側室5内の圧力により伸縮方向を検知する検知部10を備える。【選択図】図1
