Abstract: PROBLEM TO BE SOLVED: To provide a rotary joint capable of rotating the part on the lower side of the knee joint of an artificial leg for a femoral long stump. SOLUTION: A screw part 30a is formed on the upper end side of the outer periphery of the inner coupler 30 constituting a bearing mechanism part and threaded with a screw part formed on the inner periphery of the lower end of a socket 80 to be fixed with the socket 80. Accordingly, the rotary joint can be reduced in its height as a whole and a femoral part can be incorporated in the artificial leg for a disabled person with a long cut femur (long stump).
