A fluid pump enabling circulation of a working fluid in a Rankine cycle system etc. without utilizing electrical energy and able to be realized at a low cost, provided with a water pump for pumping up working fluid (water) from a steam condenser of the Rankine cycle system and feeding it to a boiler, a fluid vessel, a heater heating and vaporizing working fluid in the vessel, and a cooler cooling and liquefying the steam obtained by vaporization at the heater. Further, the fluid vessel is provided with a vibrator storing expansion energy by the expansion pressure of the steam heated by the heater. When the cooler causes the steam to condense and the pressure falls, the energy stored in the vibrator is used to feed working fluid to the heater 12 where the working fluid is then heated.
