Abstract
In a vehicular damper with a vehicle height adjusting function, a pressure source for adjusting the vehicle height is integrally assembled into the damper to improve the ease with which the damper is assembled into a vehicle body. For that purpose, on an outer peripheral portion of a damper main body there is provided a case which is connected to a damper rod and which is vertically movable. A refrigerant which varies between a gaseous phase and a liquid phase is contained in the case in a hermetically sealed manner. An electric heater is disposed inside the case to heat and evaporate the refrigerant by the electric heater. The vehicle height is increased by an increase in the vapor pressure inside the case.
