Title: LOAD DETECTOR AND LOAD DETECTING SYSTEM
Abstract:
This load detector is provided with: first and second beam-shaped strain bodies (21s, 22s) each of which has a free end (21sf, 22sf) by virtue of being cantilevered on first and second base portions (11b, 12b); a loading portion (3) which has first and second linking portions (331, 332) linked to the first and second beam-shaped strain bodies, and which is supported by means of the first and second beam-shaped strain bodies in such a way as to be capable of moving up and down; and one or more strain gauges (21g, 22g) attached to at least one of the first and second beam-shaped strain bodies. The first beam-shaped strain body extends obliquely with respect to the second beam-shaped strain body. In the direction of a bisector of an angle defined between the directions in which the first and second beam-shaped strain bodies extend, the free end and a fixed end of the first beam-shaped strain body are respectively on the free end side and the fixed end side of the second beam-shaped strain body. The distance between the free ends of the first and second beam-shaped strain bodies is greater than the distance between the fixed ends of the first and second beam-shaped strain bodies. The first and second linking portions are linked respectively to the first and second beam-shaped strain bodies at the free end sides thereof.
