A spherical joint includes a basis with spherical socket and conical groove on its end, a ball head with a rod, an elastic axial holder as a conical washer made of separate sectors. The plane of the end of the basis goes through the center of the spherical socket, and its conical groove has slot profile. Separate sectors of the elastic axial holder at the side of the ball head are arranged with lugs bent oppositely from the surface and forming together in circle a semi-cylindrical groove. At that a spiral closed spring with elastic surrounding the lugs of all the separate sectors of the elastic axial holder is installed there. |
