In this study, a spring tightening and loosening device is investigated for the development of a robot prosthesis with a variable stiffness function. This mechanism has a spiral bolt-like shape and grips a spring as a cover. We have confirmed that the proposed mechanism works and is effective, and we are aiming to realize an electrically driven mechanism in the future. This paper describes the development of an effective power transmission mechanism for the proposed structure. In this study, we proposed and fabricated a mechanism based on a superimposed structure of square columns that can accommodate variable lengths of the transmission section. Although some accuracy issues were identified, variable spring compression could be achieved, demonstrating the effectiveness of the proposed mechanism.
