A liquid pressure-feed device is provided wherein, even with a third shaft disposed between a pivot shaft and a second shaft, a sub-arm positioned between the pivot shaft and the second shaft does not obstruct movement of the third shaft. A snap mechanism has a pivot shaft supported within a closed vessel, a float arm and a sub-arm both adapted to rotate about the pivot shaft, a first shaft supported by the float arm, a second shaft supported by the sub-arm, and a spring mounted between the first and second shafts. A liquid discharge valve has a third shaft supported by the float arm, a liquid discharge valve arm mounted to the third shaft, and a liquid discharge valve body mounted to the liquid discharge valve arm to establish and block communication between the interior of the closed vessel and a liquid discharge port. The third shaft is disposed between the pivot shaft and the second shaft and a window is formed in the sub-arm so as not to obstruct movement of the third shaft. |
