A suspension device is described for an automobile, comprising: a shock absorber provided with a damping force change-over mechanism; sensor means including means for detecting horizontal and vertical vibration of the vehicle body; and control device which detects a sustaining time period of an output of the sensor means exceeding a determination value. The control device outputs a change-over for changing a damping force of the shock absorber to a large value only when the sustaining time period exceeds a predetermined time period. It also outputs a signal for maintaining the damping force of the shock absorber to be a large value for a predetermined time period even through the output of the sensor disappears.
