LOAD SENSOR AND LOAD DETECTING DEVICE

摘要

A load sensor is provided with a seat mounting hole between both end parts of a rectangular plate-like main body portion of a load receiving member. A plurality of strain detecting elements the resistance value of each of which changes depending on the amount of strain of the main body portion are disposed around the seat mounting hole. In plan view of the load receiving member, the center point of the seat mounting hole is offset from the center point of the arrangement of the plurality of strain detecting elements toward a part of the load receiving member that has relatively high rigidity.
