The spring-length changing unit (250) changes a length of the spring (500) in accordance with an amount of oil in a jack chamber (60) that accommodates the oil. The first valve (301) opens and closes a first communication path in which the oil supplied from a pump (600) is oriented toward a reservoir chamber (40) that stores the oil. The control valve (305) opens and closes a discharge flow path oriented toward the reservoir chamber (40) from a chamber (B1) that accommodates the oil to close the first valve (301). The second valve (302) opens and closes a second communication path in which the oil supplied from the pump (600) is oriented toward the jack chamber (60) when the first valve (301) is closed.",
