ラミツクス部材と金属部材との接合構造。 The shaft portion of the ceramic member and the cylindrical portion of the metal member are brought into a fitted state, and an intermediate material is interposed between the outer surface of the shaft portion and the inner surface of the cylindrical portion, and they are joined by shrink fit due to the difference in coefficient of thermal expansion. In the joining structure of a ceramic member and a metal member, the intermediate material is made of a material that does not chemically bond with the ceramic or metal and has at least one of elastic modulus and yield strength lower than that of the metal, The inner diameter of the end of the shaft insertion side of the cylindrical portion increases toward the end, and the intermediate material is interposed between the outer surface of the shaft and the inner surface of the cylindrical portion. A joining structure between a ceramic member and a metal member, characterized by shrink-fit joining due to the difference in coefficient of thermal expansion.
