<p>A combination torsion spring whereby a predetermined reaction force is suitably generated in the coil circumferential direction without the center of a wound coil tilting even when applied with a load. The first torsion spring (110) and the second torsion spring (120) of a combination torsion spring (100) are each provided with a coil (111, 121). Each coil (111, 121) is formed by spirally winding a copper wire in a different winding direction from one another. The inner diameter of the coil (111) of the first torsion spring (110) is approximately the same as the outer diameter of the coil (121) of the second torsion spring (120). In the combination torsion spring (100), the coil (121) of the second torsion spring (120) is inserted into the coil (111) of the first torsion spring (110).</p> |
