PROBLEM TO BE SOLVED: To provide a liquid force feed device capable of moving a motive power transmission shaft in a snap in the initial height of liquid gathered in a sealed vessel. SOLUTION: This device is constituted so that a float 10 is arranged in the sealed vessel 4 provided with a hydraulic fluid introducing port 9, a hydraulic fluid discharge port 5, a liquid inflow port 6 and a liquid discharge port 7; and opening-closing of an air supply valve element 22 for opening and closing an air supply valve port 20 of the hydraulic fluid introducing port 9 and an exhaust valve element 19 for opening and closing an exhaust valve port 21 of the hydraulic fluid discharge port 5, is switched by moving the motive power transmission shaft 11 in a snap by operating a snap mechanism 25 by buoyancey of the float 10 in response to the height of a liquid level of liquid gathered in the sealed vessel 4. The snap mechanism 25 is composed of a magnet 27 fixed to the motive power transmission shaft 11, an upper magnetic substance 28 fixed to an upper part of the magnet 27, and a lower magnetic substance 30 fixed to a lower part of the magnet 27.
