。[Claims for Utility Model Registration] 1. In a sliding bearing using a ceramic material as a sliding member, the rotating side sliding member is made of a ceramic material, and the sliding member has a stepped portion on one side of its outer circumferential surface. The sliding member is fitted into a metal sleeve having a large diameter portion with a threaded portion at the other end with a gap, one side of the sliding member is in contact with the stepped portion, and the other side is A ceramic bearing characterized in that the metal sleeve is fixed by being tightened with a nut fitted into the threaded portion, and is attached to a rotating shaft. 2. The ceramic bearing according to claim 1, wherein the part of the nut that comes into contact with the ceramic sliding member is formed thin without a screw. 3 Utility model registration in which the gap between the inner surface of the ceramic sliding member 5 and the fitting surface of the metal sleeve is such that thermal expansion will not cause a problem, and semi-drying adhesive is applied to the gap. A ceramic bearing according to claim 1.
