PROBLEM TO BE SOLVED: To provide a liquid pressure-feed device having a reduced number of parts and a simple structure. SOLUTION: A closed container 2 is provided with a working fluid inlet port 11, a working fluid discharge port 13, a liquid inlet port 16, and a liquid discharge port 17. A float 3, a switching valve 4 and a snap mechanism 5 are contained in the closed container 2. The float 3 is connected to a float arm 22 and the switching valve 4 is connected to a sub-arm 23. There is provided a stopper shaft 40 supported within the closed container 2. A first float arm window 41 through which the stopper shaft 40 extends and which restricts a rotational range of the float arm 22 with floating of the float 3 is open in the float arm 22, and a first sub-arm window 42 through which the stopper shaft 40 extends and which restricts a rotational range of the sub-arm 23 with descent of the float 3 in the sub-arm 23. A second float arm window 60 is open in the float arm 22 symmetrically with the first float arm window 41 relative to a line extending from the line connecting a pivot shaft 21 and a first shaft 24.
