Beschreibung
Zusammenfassung:	A spherical element whose external peripheral surface is coated with a thin heat resisting resin film and said spherical element is set into the inside of a metal mold provided with a molding chamber for casting a socket for embracing the spherical element, and then a molten metal is poured into the metal mold for forming the socket and is solidified to cast the socket that embraces the spherical element and this cast socket is removed from the metal mold and the heat resisting resin film remaining on the external peripheral surface of the spherical element is removed mechanically or chemically thereby forming a clearance that permits the free rotation of the spherical element with respect to the socket in the external peripheral surface of the spherical element and the inner surface of the socket.
