Abstract
An integrally-molded ceramic cylindrical alignment sleeve is composed of a cylindrical sleeve body and at least three convex portions located on the inner surface of the sleeve body, each of the convex portions extending from one end to the other in the longitudinal direction of the sleeve body, with the upper surface of each of the convex portions being formed in the shape of a reverse arc and the section where each of the convex portions connects to the inner surface of the sleeve body being in the shape of a continuous R. A method of producing this integrally-molded ceramic cylindrical alignment sleeve is disclosed.
