軸とセラミツクス軸との結合構造体。[Claims for Utility Model Registration] (1) A joint structure between a metal shaft and a ceramic shaft, which is formed by abutting a metal shaft and a ceramic shaft and joining them via a cylindrical metal intermediate sleeve attached to the outer circumferential surface of this abutting portion. In the body, a metal shaft and a ceramic shaft are abutted with a small gap provided, and a metal intermediate sleeve attached to the outer peripheral surface of this abutting portion and one metal shaft are welded together at a location far away from the abutting position, and The outer periphery of the abutting end of this metal shaft is notched long in the axial direction, and a gap is provided between the metal intermediate sleeve and the other ceramic shaft. A joint structure of a metal shaft and a ceramic shaft, characterized in that the end of the sleeve on the ceramic shaft side is tapered or curved so that the thickness gradually decreases. (2) The metal intermediate sleeve and the other ceramic shaft are joined through an intermediate cylindrical body made of a material that has a coefficient of thermal expansion between the two and has good bondability with both, Further, the metal shaft and the ceramic shaft according to claim 1 of the above-mentioned utility model registration claim, wherein the metal shaft side of the metal intermediate sleeve has a wall thickness/diameter ratio as small as possible in terms of strength compared to the ceramic shaft side. binding structure.
