Claims

[Scope of utility model registration request]

a shock absorber for a left and right suspension system whose damping force is variable according to the operation of an actuator; a distance to the ground detecting means for detecting a distance to the ground of the bottom of the vehicle at approximately the center in the width direction of the vehicle;
Comparison means for comparing the ground distance detected by the ground distance detection means with a reference distance and outputting a signal when the former is less than the latter; and control for controlling the damping force of the shock absorber to increase based on the output signal of the comparison means. A damping force control device comprising means.
