PURPOSE:To prevent the occurrence of lateral movement at a loading point, by connecting both ends of beams, which are laminated in two layers by connecting parts, making the central parts of the respective beams a load introducing part and a fixed supporting part, and attaching strain gages to the beams. CONSTITUTION:Two beams 7 and 8, which are thin in the direction of a load, are laminated in two stages. Both ends of said two beams 7 and 8 are connected so as to form a unitaly body by connecting parts 10 and 11. The center of one beam 7 is made to be a load introducing part and the center of the other beam 8 is made to be a fixed supporting part. Thus a sensing part is formed. Then, strain gages S1-S8 are attached to bending moment generating parts of the two beams 7 and 8. |
