PURPOSE:To reduce the number of parts and to make the scale light weight, by attaching a load cell to a cover which covers the upper part of a case containing constituent parts, thereby eliminating a base at the bottom. CONSTITUTION:Three - four pieces of legs 2 are screwed into the bottom surface of a case 1 so that the height can be freely adjusted. The opening at the upper part of the case 1 is closed by a cover 3 comprising plastics and the like. A metal fitting 4 is inserted in a part of the lower surface of said cover 3. A fixing part 6 of a load cell 5 is connected to the metal fitting 4 by screws. A spacer 8 is provided at a pressure receiving part 7 of the load cell 5. The central part of a pan receiving frame 9 made of a metal plate such as aluminum having elasticity is connected to the pressure receiving part 7 by screws. In this constitution a rigid base is not required to be provided at the bottom part of the case, the number of parts can be reduced, and the scale can be made light. |
