To provide a suspension device that can be downsized in whole and can be configured simply.SOLUTION: A suspension device 1 comprises: a hydraulic damper 3 having a rod 11 with a valve 13 that is displaced between a first liquid chamber 6 and a second liquid chamber 7 to generate liquid pressure; and an electric damper 8 that makes an actuator electrically displace the rod 11. The electric damper 8 comprises: an outer cylinder 4; an inner cylinder 5; a piston 12 provided in the rod which strokes in the inner cylinder 5; and a groove 31, provided in a center part 32 of the inner cylinder in which the piston strokes inside the inner cylinder 5, through which a first liquid chamber 6 and a second liquid chamber 7 at both end sides in an axial direction of the piston 12 are communicated with each other.SELECTED DRAWING: Figure 1

    【課題】全体に小型化できて、簡易に構成できるサスペンション装置を提供する。【解決手段】サスペンション装置1は、第1の液室6と第2の液室7との間で変位することで液圧を発生させるためにバルブ13を備えるロッド11を有する液圧式ダンパ3と、アクチュエータによって電気的にロッド11を変位させる電動ダンパ8と、を備え、電動ダンパ8は、外筒4と、内筒5と、内筒5内でストロークするロッドに設けられたピストン12と、内筒5の内側におけるピストンのストロークする内筒中央部32に設けられピストン12の軸方向両端側の第1の液室6と第2の液室7とを連通させるための溝31と、を備えている。【選択図】図1
