メタルシャフトの接合構造。A small-diameter convex portion having a groove along the circumferential surface is provided at the tip of the ceramic shaft, and a concave portion into which the convex portion fits and a plurality of screw holes in the flat diameter direction are provided on the metal shaft. When the set screw is fitted into the recess and the set screw having a tapered surface near the tip is screwed into the screw hole, the relative position is such that the conical surface of the set screw engages with the side wall surface on the tip side of the groove. is determined, and by screwing in a set screw with the convex portion and recess fitted, the tapered surface of the set screw presses the groove side wall surface in the axial direction, and the end face of the metal shaft is pressed against the stepped portion of the ceramic shaft. A joining structure of a ceramic shaft and a metal shaft, characterized in that both shafts are fixed together by pressing.
