Abstract:
1. A load measuring apparatus, comprising: a long and narrow beam member having a loading section provided at one end; a supporting member for supporting the beam member at a side closer to the other end of the beam member than the loading section; and a displacement sensor provided in such a manner as to be able to measure a displacement of the loading section, wherein: the beam member includes a pair of long and narrow leg portions arranged in parallel to each other while being spaced apart in a thickness direction and a connecting portion which connects ends of the respective leg portions at a side of the loading section, the beam member including bent opposite end parts of a long and narrow member bent in a same direction at right angles to a central part so that the central part forms the connecting portion and the bent opposite end parts form the respective leg portions, the beam member is slidably supported on the supporting member along a length direction of the respective leg portions so as to be able to change a length between a supported position by the supporting member and the loading section; the loading section includes a needle-shaped tip and is fixed to the one end of the beam member so as to perpendicularly project from a surface of one of the leg portions; and the displacement sensor is adapted to measure a displacement in a projecting direction of the loading section.
