Suspension device for vehicle

Provided is a suspension device for a vehicle, the suspension device being configured so as to prevent a deterioration in hydraulic balance caused by the leakage of hydraulic oil in the upper chambers and lower chambers of a pair of hydraulic suspension cylinders, the upper chambers and the lower chambers being cross-connected, or by other causes. The suspension device for a vehicle is provided with: a first oil path by which a first upper port which is open in a first hydraulic cylinder and a first lower port which is open in a second hydraulic cylinder are connected so as to communicate with each other; a second oil path by which a second upper port which is open in the second hydraulic cylinder and a second lower port which is open in the first hydraulic cylinder are connected so as to communicate with each other; a first hydraulic damping mechanism which is provided in the first oil path; a second hydraulic damping mechanism which is provided in the second oil path; a first accumulator which is connected to the first oil path through a first branch oil path having a first auxiliary hydraulic damping mechanism; a second accumulator which is connected to the second oil path through a second branch oil path having a second auxiliary hydraulic damping mechanism; and a bridge oil path which connects the first branch oil path and the second branch oil path.
