金属部材とセラミツク部材の結合構造。[Claims for Utility Model Registration] A flange surface of a metal member and a flange surface of a ceramic member are butted together, and a ring-shaped metal spacer is externally fitted onto one of the butted members and abuts against the back surface of the flange of the member. A pressing force applied in the axial direction through the metal spacer by a cylindrical connecting fitting that is attached to the flange of the other member and is fitted so as to surround the metal spacer and the flange of both members. The flange surfaces of both members are held in close contact by The size is the following formula (1): 1 α 1 + 2 α 2 ≧ ( 1 + 2 ) α 3 ...
(1) [In the formula, 1 : Axial length (thickness) of the flange of the member to which the metal spacer is fitted, 2 : Axial length of the metal spacer α 1 : The metal spacer is fitted to the outside Coefficient of thermal expansion of the flange of the member α 2 : Coefficient of thermal expansion of the metal spacer α 3 : Coefficient of thermal expansion of the cylindrical connecting fitting .
