METHOD FOR RETAINING BENDING ANGLE OF BENT PIECE AND BENDING ANGLE RETAINING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a method and a structure for retaining a bent piece at a right angle without producing any breakage or bending damage. SOLUTION: A hooking protrusion b extending from one side to the other side to cross-over the extension of a crease line a by a protruding amount at least smaller than the thickness of the substrate 1 is provided between the substrate 1 and the bending piece 2 by cutting a desired location of the crease line a for forming the bending piece 2. The hooking protrusion b extending out of the substrate 1 side can be separated from the bending piece 2 when the bending piece 2 is bent. The hooking protrusion extending out of the bending piece 2 side can be separated from the substrate 1 when the bending piece 2 is bent. A face b" near an extending separate end surface b' of the hooking protrusion b extending out of the substrate 1 when the bending piece 2 is bent is engaged with a separating end surface 2' at the bending piece 2, and a surface of the protrusion extending out of the bending piece 2 near the extending separation end surface is hooked with the separating end surface at the base plate 1.
