Abstract: A force feedback device is provided. Several spring-sleeved screw bolts respectively pass through the suppression holes around the top cover to fix the top cover on the base. Each spring in the ladder-shaped suppression hole is suppressed between the nut of the screw bolt and the top cover. Since the body of the screw bolt is longer than a predetermined height of the suppression hole, an absorption gap is reserved between the nut and the top cover to provide a smooth feel in operating the joystick.
