SUSPENSION DEVICE

A suspension device includes: a hydraulic damper including a rod provided with a valve for generating a hydraulic pressure when the rod is displaced between a first liquid chamber and a second liquid chamber; and an electric damper configured to electrically displace the rod by an actuator. The electric damper includes: an outer cylinder; an inner cylinder; a piston provided on the rod and configured to stroke in the inner cylinder; and a communication passage disposed inside the inner cylinder at a central portion where the piston strokes. The communication passage establishes communication between the first liquid chamber at one axial end side of the piston and the second liquid chamber at another axial end side of the piston.
