To provide an electromagnetic shock absorber capable of improving a mounting property to a vehicle, reducing weights and costs, and materializing smooth expanding/contracting action, without impairing cooling performance.SOLUTION: An electromagnetic shock absorber D1 includes a non-magnetic cylinder 1, a piston rod 2 movably inserted in an inner periphery of the cylinder 1, a piston 3 that is slidably inserted in the cylinder 1, is provided on the piston rod 2, and partitions the inside of the cylinder 1 into an expansion side chamber R1 and a pressure side chamber R2, a linear motor LM that has a cylindrical movable element M installed to the piston rod 2 and a cylindrical stator S provided on an outer periphery of the cylinder 1 and opposite to the movable element M, a working liquid filled in the expansion side chamber R1 and the pressure side chamber R2, an attenuation passage P communicating the expansion side chamber R1 and the pressure side chamber R2, and an attenuation valve V giving resistance to a flow of the working liquid passing through the attenuation passage P.SELECTED DRAWING: Figure 1

    【課題】冷却性を損なわず、車両への搭載性の向上と、重量およびコストを低減できるとともに、円滑な伸縮作動を実現できる電磁緩衝器の提供である。【解決手段】本発明の電磁緩衝器D1は、非磁性体のシリンダ1と、シリンダ1の内周に移動自在に挿入されるピストンロッド2と、シリンダ1内に摺動自在に挿入されるとともにピストンロッド2に設けられてシリンダ1内を伸側室R1と圧側室R2とに区画するピストン3と、ピストンロッド2に装着される筒状の可動子Mとシリンダ1の外周に設けられて可動子Mに対向する筒状の固定子Sとを有するリニアモータLMと、伸側室R1と圧側室R2とに充填される作動液体と、伸側室R1と圧側室R2とを連通する減衰通路Pと、減衰通路Pを通過する作動液体の流れに抵抗を与える減衰バルブVとを備えている。【選択図】図1
