PURPOSE:To protect a load-cell from overload in a simple constitution, by attaching the load-cell to a cover that covers the upper part of a case, and providing a stopper at a facing part between a receiving pan which is connected to the load-cell and the cover. CONSTITUTION:A metal fitting 4 is inserted in a part of the lower surface of a cover 3. A fixing part 6 of a load-cell 5 is connected to said metal fitting 4 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. When an excessive load is applied on the receiving pan 10, the stopper 11 of the cover 3 supports the receiving pan 10. When a material is mounted on the vicinity of the edge part of the receiving pan 10, the receiving pan 10 is elastically deformed and supported by the upper surface of the edge part of the cover 3. Thus, the load-cell 5 can be protected from overload. |
