ル。A double-sided shear type load cell main body consisting of end parts located on both sides of the middle part of the middle part on which the load is applied and connected to the fixed side, and a lower end of the bottom face of a recess formed in the center of the upper surface of the middle part. A double-sided shearing type load cell is provided with a seat fitted so as to come into contact with the seat, and is configured to create friction between the seat and the upper surface of the intermediate portion (and apply a load via the seat).
