PROBLEM TO BE SOLVED: To provide a model of a topological-soliton circuit that is easily assembled or decomposed, is extremely easily reset to an initial state, and can easily change a parameter if necessary. SOLUTION: An elastic shaft member 11 is provided that has a length of the axial direction in the one-dimension direction, stores elastic energy as a restoring force when it is twisted in the circumference direction about the center axis, shortens the outer diameter in the radial direction when a tensile force is applied axially and it is axially extended, and has a restoring force also in the axial direction. A plurality of unit cells 12 are fixed at intervals in the axial direction of the shaft member 11. Each unit cell 12 has a through hole 13 for penetrating the shaft member 11 in a fixed part 21, and the center of gravity is located at a position different from the position having the through hole 13. The inner diameter of the through hole 13 is smaller than the outer diameter when no tensile force is applied to the shaft member 11, but the diameter of the shaft member can be reduced to a diameter smaller than the inner diameter of the through hole when the tensile force is applied to the shaft member 11.
