摘要： An integral type second lever constituting member (A) is mounted on a constitution, in which a first lever member (5) is assembled in a Roberval's mechanism composed of a stationary block (1), a floating frame (2) and upper and lower sub-levers (3, 4). The integral type second lever constituting member (A) is mounted by mounting a force point portion (9) and a fulcrum portion (8) on the Roberval's mechanism through screw-fastened holes (8a, 9a), thereby to assemble a load measuring mechanism as a whole. At the screw-fastening time, the turning torque of the screw is supported by a connecting portion (10), and this connecting portion (10) is removed after the integral type second lever constituting member (A) was mounted. In the load measuring mechanism of an electronic balance, the second lever member can be mounted easily and reliably.
