ABSTRACT:
An artificial joint comprising a first member including a butt portion located at one end of the first member and having an internal opening and a long guide groove extending to the opening and a second member in contact with the butt portion of the first member and including an expanded portion at one end of the second member. The expanded portion is fitted in the internal opening of the first member. A projection along both sides of the long guide groove prevents the expanded portion from separating from the internal opening except at prescribed positions of the first and second members. The long guide groove guides the movement of the second member as it bends relative to the first member in a prescribed direction.
