PROBLEM TO BE SOLVED: To obtain a method for manufacturing a lashing hook, which facilitates securing of dimension accuracy, and to provide a structure of a lashing hook.;SOLUTION: The method for manufacturing a lashing hook includes: a first step of bending each of parts divided by a cutting part 42 in a plate material 40 so as to form folding lines 44A, 44B each substantially perpendicular to the cutting part 42 to form a rear side first flange 30 and a rear side second flange 32 on both sides that are interposed by the cutting part 42 therebetween; a second step of bending a part that has been an extending part 46 of the cutting part 42 in the plate material 40 after the first step to overlap the rear side first flange 30 and the rear side second flange 32; and a third step of joining the parts of the rear side first flange 30 and the rear side second flange 32 that are overlapped in the second step, by arc welding.;COPYRIGHT: (C)2012,JPO&INPIT
