THREE-DIMENSIONAL PUZZLE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensional puzzle structure capable of surely increasing connection strength when being assembled while eliminating the exposure of a joined part to an outer surface in the three-dimensional puzzle structure for assembling sheet-like parts of paper or the like and turning them to a three-dimensional structure. SOLUTION: A projected sheet body 1 and a recessed sheet body 2 are connected and fixed by fitting the projection part 14 of the projected sheet body 1 so as to insert it to the recessed part 24 of the recessed sheet body 2.
