Claims

[Scope of utility model registration request]

A Roberval mechanism in which a load transmission protrusion is formed on the saucer connecting portion side is provided, a load cell having one end fixed to the fixed portion side of the Roberval mechanism is provided, and the load receiving portion of the load cell and the load transmitting projection of the Roberval mechanism are connected to each other. A load in which connecting holes each having a tapered portion on at least one edge are formed on the same axis, threaded portions to be inserted into these connecting holes are provided at both ends, and a flexible portion that does not expand or contract in the axial direction is provided in the middle portion. A pair of fixtures including fixtures having a conical surface that form a transmission body and fit into the tapered part are provided for each of the threaded parts, and these fixtures connect the threaded parts at both ends of the load transmission body to the load cell. A load cell scale, wherein the load cell scale is fixed to the load receiving portion and the load transmitting protrusion of the Roberval mechanism.
