摘要： A height control device for vehicle for maintaining constant a height from a wheel-side member to a body-side member of a vehicle, including expansive operation means provided on the wheel-side member to support the body-side member and adapted to be expanded and contracted in a direction of the vehicle height by supplying and discharging an operating fluid with respect thereto; link means provided between the wheel-side member and the body-side member to connect each other and adapted to be operated in response to a change in the height between the wheel-side member and the body-side member; control means connected to an operation output portion of the link means to control supply, discharge and stop of the operating fluid with respect to the expansive operation means in response to the operation of the link means; damper means provided at the operation output portion of the link means to damp a relatively short fluctuating operation of the link means to restrict a responsive operation of the control means and to allow a relatively long ordinary operation of the link means to responsively operate the control means; and elastic means provided at a portion of the link means on the side of the wheel-side member away from the operation output portion connected to the control means to elastically absorb and accumulate an operating force of the link means to ordinarily operate the link means. In such a mechanical height control device for vehicle, a vehicle height can be maintained constant irrespective of a change in load on the vehicle, and the operation of the control means is suppressed in response to high-frequency vibration during running of the vehicle.
