A suspension device for a vehicle

Providing a suspension apparatus of a vehicle, to suppress deterioration of the balance associated with leakage in the oil chamber of the suspension cross-connect to the hydraulic cylinder / chamber under hydraulic pressure or the like caused. The vehicle suspension device comprising: a first oil passage which makes communication port connected to the first upper and a second lower port to the second hydraulic cylinder openings formed in the first cylinder opening formed therein; a second oil, which on the upper side of the second port and the first port on the lower side of the first hydraulic cylinder opening formed in the second hydraulic cylinder connected to the communication opening formed; a first hydraulic damping means, which is provided at the an oil path; a second hydraulic damping means, disposed in the second oil passage; a first accumulator, which is connected to the first oil passage through the first branch passage having a first auxiliary hydraulic damping mechanism; a first two accumulator, which is connected via a second oil passage and the second branch passage having a second auxiliary hydraulic damping mechanism; bridge passage, which causes the phase between the first branch passage and the second branch passage connection.
