定用ロードセル。[Claims for Utility Model Registration] (1) The load of the object to be measured is applied to the approximately central portion of the flexure-generating body disposed approximately horizontally, thereby deforming the flexure-generating body and electrically discharging the load of the object to be measured. 1. A load cell for measuring a heavy object, characterized in that a pin is inserted through and arranged near both ends of a flexure element, and the flexure element is supported via the pins. (2) The formation position of the pin insertion hole in the flexure element is
A load cell for measuring a heavy object according to claim (1) of the utility model registration, characterized in that the flexure element is at or near a portion where the expansion and contraction of the flexure element is least when the flexure element deforms. (3) By forming the inner diameter of the pin insertion hole to be slightly larger than the outer diameter of the pin inserted into the pin insertion hole, a gap is formed between the pin and the pin insertion hole,
A load cell for measuring a heavy object according to claim (1) or claim (2), characterized in that the deformation of the flexure element is ensured by this gap as well.
