Abstract of the Disclosure This invention is, characterised in that a ceramic rotary ring wherein an axial hole for engaging an axis is formed at the center thereof and a plane which is approximately right angle with respect to the axial center of the radial hole and a ceramic fixed ring wherein a plane which opposes to the plane formed at said ceramic rotary ring and formed approximately rectangular to said axial center and forming a ring shape projection allowed to correspond its center to said axial center at either one of a plane formed at said ceramic rotary ring or said ceramic fixed ring, and a ring shape groove correspond to said ring shape projection, said ring shape projection being engaged thereto. when the sliding surface is formed by the groove and the projection engaging the projection to the groove, and further when the top end of the projection and the bottom of the groove are constructed as a sliding surface, only the thrust load can be supported. Further, when the top end of the projection and the bottom of the groove, and the side of the projection and the side of the groove are constructed as sliding surfaces respectively, both the thrust and the radial loads can be supported simultaneously. Further, the planes formed at the rotary ring and the fixed ring are constructed as sliding surfaces respectively, the thrust load is can be supported by said planes. The radial load can be supported by the projection and the side of the groove. Further, since the center of the groove and the projection are allowed to correspond to the axial center respectively, the axial fluctiation of the center with respect to the fixed ring can be prevented.
