PROBLEM TO BE SOLVED: To provide a load cell of Roberval type of which the strain-causing part formed in one arm part with the same thickness is pasted with a strain gauge and is constituted by providing a thickness difference between the two arm parts so as to reduce the effects of bending of the strain-causing body. SOLUTION: In the load cell forming a Roberval mechanism consisting of the two parallel arm parts formed in between a fixed end and movable end and four strain-causing parts connected with the two arm parts two by two, the four strain-causing parts are formed in the same thickness. The two arm parts are constituted of the first arm part where each strain gauge is pasted on the two connected strain-causing parts, and the second arm parts of which the thickness is formed thinner than the first arm part. Therefore, balance of strain loaded on the strain-causing part where the strain gauge is pasted on can be attained. COPYRIGHT: (C)2006,JPO&NCIPI
