SOLUTION: The weighing apparatus comprises a weighing space, where liquid foods are measured, a weighing feed pipe for feeding the liquid foods weighed in the weighing space, and a nozzle body attached to the supply pipe. A weighing pump for conducting weighing action is communicated with the weighing space, and a cylinder 76 and a piston 74, which constitute the weighing pump are sealed by the diaphragm 71. An annular projection is provided on the diaphragm and an annular recess 80 is provided in the piston. The projection of the diaphragm is fitted lockingly into the recess of the piston, and the interior of the piston is evacuated to further ensure fixation.
