Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a joint mechanism appropriate for a rotary joint to be used for a joint mechanism of a robot to be used in space, and to provide a rotary joint. SOLUTION: In this joint mechanism for transmitting the force from a primary side to a secondary side, an elastic body and a preload generating means for giving a selected preload to the elastic body are arranged between a primary side member and a secondary side member. The elastic body is energized by the preload selected by the preload generating means so that a phase difference between them becomes zero. When the force more than the selected preload is applied between both the members, this variable holding force joint is characterized to generate a phase difference between them.
