摘要： PROBLEM TO BE SOLVED: To improve measurement accuracy and efficiency in operation by protruding the terminals of a measuring device main body at an interval of a reference length, installing a bend measuring device to the center part between the terminals of a measuring device main body, and bringing the tips of both terminals into contact with the edge of a steel sheet whose lateral bend is to be measured. SOLUTION: A measuring device main body 11 is constituted of a square bar formed of a hardly deformable light alloy, and a dial gauge as measuring instrument 13 is installed in the center of the measuring device main body 11. Terminals 12 with a length of approximately 15 mm are protruded at the locations of a reference length, and guide plates 16 for bringing the terminals 12 into contact with the edge of a steel sheet are installed on the measuring device main body 11. First, a handle 14 is held by a hand to bring the terminals 12 at both ends of the measuring device main body 11 into contact with a ruler having no bend to verify the zero point of the measuring instrument 13. Next, the steel sheet is placed still on an inspection base or a surface plate without tension, and the terminals 12 at both ends of the measuring device main body 11 are bought into contact with the edge part of the steel sheet via the guide plates 16. Then the dial gauge of the measuring instrument 13 is operated to measure the amount of a lateral bend.
