Abstract
A case is provided on an outside of a damper main body that is connected to a damper rod and which can freely move in vertical directions. A pressure chamber is formed between the damper main body and the case in which a pressure medium is sealed up, which pressure medium changes its phase between vapor and liquid phases. The pressure medium is heated and vaporized by heat generated by virtue of a damping effect of the damper, while the pressure medium is condensed by virtue of heat radiating from the case by running wind. During the running on a rough road when the heating value of the damper becomes large, the internal pressure of the pressure chamber is increased to thereby raise the vehicle height, and during the running at high speeds when the heat radiating value becomes large, the internal pressure of the pressure chamber is decreased to thereby lower the vehicle height.
