  • Load sensor equipped with strain-generating member having strain elements with tube spacer for eliminating clamping force
    Patent number: 6677539
    Abstract: A load sensor is assembled by screwing a nut on a bolt, sequentially fitting a washer and a tube spacer on the bolt, fitting a bore of a strain-generating member on the tube spacer, fitting another washer on the bolt, tightening another nut, and clamping a bobbin-shaped unit composed of the washers and the tube spacer between the nuts in the axial direction of the bolt. Since the strain-generating member having a thickness less than the height of a strain-generating member holding space formed between the washers is placed in the space with some clearance, even when the washers are fixed to the bolt by a strong pressing force, the pressing force will not directly act on the strain-generating member.
