Claims

[Scope of utility model registration request]

The actuator motor is disposed within the piston rod and controls the damping force of the vehicle, and the control valve is connected to the rotating shaft of the motor, and when the motor is energized, the oil control hole of the valve is communicated with the oil inflow passage. The damping force control device for a vehicle is characterized in that the rotating shaft is rotated when no current is applied to cut off communication between the oil control hole and the oil inflow passage.
