PROBLEM TO BE SOLVED: To provide a liquid forcible feeder wherein an operating fluid introduction port and an operating fluid discharge port can be changed to be opened/closed over a long period. SOLUTION: A float 3 and a snap mechanism 5 are arranged in a sealed container 2 which has the operating fluid introduction port 11, the operating fluid discharge port 13, a liquid flow-in port 16 and a liquid flow-out port 17. The snap mechanism 5 comprises a float arm 34 to be rocked in response to the up-and-down movement of the float 3, a first roller 51 rotatably mounted on an rocking shaft 35 of the float arm 34, a compression coil spring 54 to be compression or elongation deformed in the axial direction of the float arm 34 in response to the rocking of the float arm 34, a second roller 52 to be moved in the axial direction of the float arm 34 in response to the deformation of the compression coil spring 54, and a third roller 53 thrust and arranged between the first and second rollers 51, 52.
