金属部材を押圧してセラミック部材と第１金属部材の結
合をより強固にする。The joining structure of a ceramic member and a metal member of the present invention is manufactured as follows. That is, the ceramic member and the first metal member are shrink-fitted, and when the ceramic member and the metal member are shrink-fitted, a predetermined gap is formed in a part of the joint, and the gap is filled with a predetermined gap. A second metal member having a hardness smaller than that of the first metal member is shrink-fitted to the second metal member.
The metal member is pressed to further strengthen the bond between the ceramic member and the first metal member.
セラミック部材と第１金属部材の少なくとも一方に溝を

な結合が得られない。The effective area of the gap provided at the joint between the ceramic member and the first metal member is desirably 172 or less of the total area of the joint, assuming that no gap is provided at the joint. If the gap area exceeds 1/2, sufficient bonding cannot be obtained in terms of safety and load resistance.
また第２金属部材は第１金属部材より硬度の小さいもの
であれば何でもよいが、第１金属部材がステンレスや耐
摩耗鋼の場合、第２金属部材としてはＣｕやＡＩ等が適
切である。Further, the second metal member may be any material as long as it has a hardness lower than that of the first metal member, but when the first metal member is stainless steel or wear-resistant steel, Cu, AI, or the like is suitable for the second metal member.
