PROBLEM TO BE SOLVED: To provide a vehicle suspension device increasing durability of a motor for generating a damping force. SOLUTION: The motor 26 generates the damping force between a sprung mass and an unsprung mass. An auxiliary damping force generating part 28 generates an auxiliary damping force of auxiliary damping force characteristics different from motor damping force characteristics played by the motor 26 between the sprung mass and the unsprung mass according to the rotational speed of the motor 26. The auxiliary damping force generating part 28 comprises a fan 60 rotating integrally with the rotor of the motor 26. The fan 60 is disposed in a container sealed with a liquid. Thus, the motor at high speeds effectively prevented from being damaged while securing controllability and responsiveness at low speeds without increasing the capacity of the motor.
