Abstract
An electric suspension device includes a cylinder, a sub-tank, a first oil passage and a second oil passage, a damping force adjusting valve, and a damping force adjusting motor. The cylinder is rotatable about a mounting axis. The first oil passage connects a first inner oil chamber and an outer oil chamber. The second oil passage connects the first inner oil chamber of the cylinder and an oil chamber of the sub-tank. The first and second oil passages are disposed outside an inner tube and an outer tube, and share a portion with each other. The first and second oil passages are entirely disposed on the same side with respect to a reference plane.
