Scale, strain generating body, and load cell

Abstract

A scale is provided with: a case base; and a case cover arranged on the case base, the case cover being configured such that a load is applied to the case cover. The scale is provided with: a plurality of strain generating bodies configured to support the case cover on the case base, the strain generating bodies each having a strain generating part, the strain generating part being configured to be elastically deformed by receiving the load applied to the case cover; and a strain sensor provided on the strain generating part of each of the strain generating bodies, the strain sensor being configured to give a resistance value varied in accordance with tension and compression due to deformation of the strain generating part. The strain sensor includes a first strain gauge and a second strain gauge, the first strain gauge being arranged at a site deformed into the recessed shape in a state in which the strain generating part is elastically deformed, and the second strain gauge being arranged at a site deformed into the projected shape in a state in which the strain generating part is elastically deformed. In a mutually adjacent pair among the strain generating bodies, the strain sensor of the strain generating body serving as a first partner is arranged on a front surface of the strain generating part, and the strain sensor of the strain generating body serving as a second partner is arranged on a back surface of the strain generating part.
