PURPOSE:To protect a load-cell from overload and to make the scale thin, by holding a pan receiving frame that holds a receiving pan in a case together with the load-cell, and facing the receiving pan the upper surface of the case with a slight interval being provided. CONSTITUTION:A spacer 8 is provided at a pressure receiving part 7 of a load cell 5, and the central part of a pan receiving frame 9 comprising a metal plate such as aluminum having elasticity is connected to the pressure receiving part 7 by screws. A stopper 11, which faces the lower surface of the center of a receiving pan 10 with a specified interval being provided, is formed at the upper surface of the center of a cover 3. The gap at the part where the cover 3 and the receiving pan 10 face is small even along the entire surface other than the stopper 11. A heaped part 12, which faces the periphery of the receiving pan 10 with a slight interval being provided, is formed at the periphery of the cover. Bosses 13, which are implanted at the four corners of the lower surface of the receiving pan 10, pierce through the cover 3 and are connected to the pan receiving frame 9 so that they can be freely attached or detached. |
