    摘要: A load cell scale, has a columnar shaped load cell part having a upper surface and a lateral surface intersecting with the upper surface, the load cell part having a first load cell with a first weighting and a second load cell with a second weighting, and a stopper part for restricting deformation occurring in the load cell, wherein the load cell part further has a strain portion capable of elastically deforming, and wherein the stopper part is a plate-shaped member formed to extend along the longitudinal direction, the stopper portion has a fixing-end portion fixed to the lateral surface of the load cell; and a free-end portion separating from the fixing-end portion along the longitudinal axis, the free-end portion being configured to restrict the elastic deformation of the load cell part due to the load in a state when the fixing-end portion is fixed to the lateral surface.

    摘要: A load cell scale has a load cell part formed in a columnar shape, the load cell part having a upper surface extending along a longitudinal axis and a lateral surface intersecting with the upper surface, and a stopper part configured to restrict deformation occurring in the load cell due to a load exceeding a predetermined value and applied to the load cell, wherein the load cell part has a strain portion capable of elastically deforming and the strain portion penetrates the load cell part from the lateral surface in a short direction orthogonal to the longitudinal direction, and wherein the stopper portion is provided to be connected to the lateral surface of the load cell part.
