PROBLEM TO BE SOLVED: To provide a puzzle rod stirring up an intellectual interest despite a relatively simple structure.SOLUTION: This puzzle rod is constituted of a plurality of spiral rods (1a-1c, 2a-2c and 3a-3c) having same wire diameter, length, rotating radius, and pitch and having a same shape. This method for creating the puzzle rod 10 which forms into a cylindrical structure when sequentially assembling the plurality of spiral rods at a prescribed sequence, includes: a step of fixing one of the plurality of spiral rods; a step of placing one of the other spiral rods along the axial direction of the fixed spiral rod from its end portion and rotatingly twisting it therearound in the circumferential direction to create a paired structure; and a step of sequentially collecting one of the other spiral rods in the same process one by one to create the cylindrical structure. |
