て荷重負荷手段から試験片に曲げ荷重を加える曲げ試験
機において、上記ころを挿入する荷重負荷手段の凹部の
深さがこる直径よりも小さく、かつ試験片の負荷時凹部

る曲げ試験機。In a bending test machine that applies a bending load to a test piece from a load-loading means through a plurality of rollers, some of which are inserted into the load-loading means, the depth of the recess of the load-loading means into which the rollers are inserted is greater than the diameter of the bending. The bending tester is characterized in that the cross-sectional area of the saw 4 of the portion inserted into the recess is smaller than the cross-sectional area of the recess so that the test piece is in line contact with the recess during loading.
