PURPOSE:To weigh weight by one load cell by supporting load of a body with plural hydraulic sensibility mechanism and further, weighing by transmitting it to a hydraulic composite mechanism via hydraulic fluid. CONSTITUTION:An oil tank 9 is pressurized by the compressed air 13. Then, the pressure is transmitted to the hydraulic fluid from the tank 9 to pressurize cylinders 2. A weighing table 1 is provided on the cylinders 2 and when the load is applied thereon, a head of cylinders 4 is pressurized via the hydraulic fluid. Then, a piston rod 3a is pressurized downward to pressurize the load cell 6. In this way, the load of the body is received by the plural hydraulic sensibility mechanisms of the cylinders 2 and then,. transmitted it to the hydraulic composite mechanism of the cylinders 4 to pressurize the load cell 6. Accordingly, since the load is weighed on the hydraulic composite mechanism, one load cell only serves for actuating, by which an instrument can be simplified.
