取付構造。[Claims for Utility Model Registration] (1) A strain gauge is attached to a thin strain-generating part formed in the center of a strain-generating body, and a strain gauge is attached to a thin strain-generating part formed in the center of a strain-generating body. In a load cell mounting structure in which a through hole for a mounting bolt is formed at one end and the other end of the strain body to provide a focus side attachment portion and a fulcrum side attachment portion, the load cell is mounted on both the fulcrum side and the focus side. Insert a mounting bolt into each through hole in the part, and tighten and fix the fulcrum side mounting part on the support base by threading the mounting bolt, and tighten and fix the emphasis plate to the emphasis side mounting part, In addition, a load cell mounting structure in a load cell type scale in which a spacer is locally interposed around the mounting bolt insertion portion between the mating surfaces of these tightening portions. (2) The mounting structure for a load cell in a load cell type scale according to claim 1, wherein a counterbore recess is formed at a location on the surface of the load cell's emphasis side mounting portion and/or the fulcrum side mounting portion at a location in direct contact with the head of the mounting bolt. (3) A counterbore recess is formed in the contact portion with the spacer on the mating surface of each tightening part of the load cell's emphasis side mounting part and fulcrum side mounting part, and the spacer is fitted into the counterbore recess, and the spacer A mounting structure for a load cell in a load cell type scale according to claim 1 or 2, wherein the diameter of the counterbore recess is smaller than that of the counterbore recess, and the length thereof is longer than the depth of the recess. (4) The load cell type scale according to claim 1 or 2, wherein an annular groove is formed around the contact portion with the spacer on each tightening portion mating surface of the emphasis side attachment portion and the fulcrum side attachment portion of the load cell. Load cell mounting structure.
